The tell is not what they say they will do to you. It is that they stop halfway through and ask what your breathing is doing. Everything worth having on the giving end of this comes from paying attention, and LewdChat's sadist chat is where the people who actually do that find the people who want them to. Free, anonymous, adults only, a nickname and you are in. If you are here because the word sounded like permission to be unpleasant, this is the wrong room and the channel will work that out inside a minute.
A sadist and someone who wants to hurt people are not the same thing
Start here, because the word does not distinguish between them and the room does.
What a sadist wants is a reaction from someone who came looking for it. The appetite is for the response, the noise, the way somebody's language falls apart when they get far enough in. Take away the consent and you have taken away the thing itself, because a reaction you extracted from someone who did not want to give it is not the same reaction. It is a different, worse object that happens to look similar from outside. Nobody in this room is confused about that, and the people who are do not last.
The scene calls the good version ethical sadism, which sounds like a contradiction and is not. It means the cruelty is real, the enjoyment is genuine, and the whole thing is aimed at someone who asked. You are not pretending to enjoy it for their sake. You do enjoy it. That is the honest part, and being honest about it is what makes you safe to hand yourself to.
Sadist is not a synonym for Dom
These get welded together and they are separate appetites. A Dom wants authority: obedience, control, the shape of a dynamic. A sadist wants a reaction. Plenty of people are both and never notice the seam. Plenty are one and not the other.
You will meet sadists in here who have no interest in running anybody's life, who would find a protocol arrangement tedious, and who want exactly one thing: a bottom who likes intensity and describes it well. You will also meet Doms who barely care about sensation at all and get everything they need from being obeyed, which is what Dom sub chat is built around. The scene shorthand is S-type and M-type, and it is useful precisely because it says nothing about who is in charge. If you top for the reaction rather than the obedience, say so when you introduce yourself. It sorts the room fast.
Reading is the whole skill
Everything good on this side of it comes down to attention, and in text that means reading how someone writes rather than what they say.
The signal is in the shape of their replies. Sentences getting shorter is usually a good sign. Sentences stopping is not necessarily. Typos climbing means they are somewhere real. A tidy, well-punctuated answer partway through a heavy scene means they are still watching from outside it, which tells you something too. Someone who suddenly goes formal, or answers a question you did not ask, has left the room in some way and you need to find out which way before you go further.
The rest is asking, which people treat as a mood-killer and is not. Checking in does not break a scene when it is done in the register of the scene. Experienced tops fold it into the thing itself, and a bottom who is enjoying themselves will answer without surfacing. Green, yellow, red does the heavy lifting here because yellow lets someone adjust without stopping, which is a gift to both of you. Safewords covers the mechanics.
What you will not find here is instruction on how to do any of this to a body. This page describes an appetite and a room. It does not teach method, and anyone in the channel handing out confident numbers about what a person can take is someone to scroll past regardless of how sure they sound.
The dilemma nobody warns you about
Sadists talk about this in the channel more than outsiders would guess: the problem of wanting more than you should take.
Somebody is giving you everything, they are past the point where they can make good decisions about themselves, and they will say yes to anything you propose. That is exactly the moment your judgment has to do the work, because theirs is offline and you put it there. The appetite says keep going. The job says the person who is furthest gone is the person least able to hold a limit, so you hold it for them. Restraint is not a failure of nerve here. It is the actual skill, and it is what separates a sadist people come back to from one they tell each other about.
The other half of it is enjoying yourself honestly. There is a version of this where the top performs reluctance, treats their own appetite as a regrettable condition, and asks to be reassured about it. Bottoms find that exhausting. The people you want are not asking you to feel bad about liking it. They are asking you to like it in a direction they chose. Say what you want plainly, own the fact that you enjoy their reaction, and then behave like someone who can be trusted with it.
Finding someone to be cruel to
They are in the masochist chat room, and the good ones are picky, which you should take as a compliment to the room rather than an obstacle. An M-type who has been around knows the difference between an advert and a person, and adverts get ignored.
So write like a person. Say what you actually want out of it, what register you run in, whether the talk goes cold and reductive (which is where this overlaps with degradation chat) or stays warm underneath the intensity, and what you will not do. Ask what their limits are before they volunteer them, because asking first is the single loudest signal you can send. Most scenes here are written impact of one kind or another, which puts impact play chat next door, and negotiating a scene is the five-minute version of settling the shape first.
Then stay for the landing. Aftercare is not a courtesy you extend afterwards, it is part of what you agreed to when you started, and text scenes drop people the same as any other kind. The tops who stick around are the ones with a queue. The wider BDSM chat room is the house this sits inside, real moderators keep it honest, and it is open at every hour.
