If it is not a case of malice but incapability of realising what they are doing you might want to be on the lookout for chances to support their social development whereever possible. That is if you are in a interaction that is clearly hurtful to you but they don't seem to see it as hurtful it would be important to make seeing the hurtfulness as easy as possible. However this should be done in a manner that doesn't step on any triggers (ie being attacking/accusing about it won't likely get results). If it is only a "technical" matter that they simply don't understand some key social fact pointing it out should not be a big drama event. Think of pointing out to someone that they missed a minus sign.
It's also easier to offer people alternative, potentially more effective, ways to get what they care about than to demand that they cease activities that get them what they want currently. It might feel silly to even having to talk about some basic things but if there is a need to talk about it then talking about it is likely to do good. The alternative on relying that people should get some social basics right on their own can leave you uncomfortably adapting to malfunction.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
