Many major social media sites, such as twitter enforce rules in a specific way so that certain groups of users are affected more than others. I hope this is not a road that bitcointalk is going down.
I haven't reviewed the deleted posts by TECHARE that he posted closely, but I would agree that at least some of them did break the forum rules around NSFW posts. Even though I don't know this to be true, I would even stipulate all of TECHARE's posts violated forum rules. However I would caution against going full Gretchen Whitmer on users, especially if they are objectively speaking making a good faith effort to debate, and engage with other forum members. If someone posts a NSFW image, [ img] it out, so it won't display by default. Off topic rules state that for a post to be on topic, it must be related to the OP of a thread, and some people are very good at making the majority of the post be off topic, and a single sentence at the end be related to the OP -- when this happens, and the off topic portion is responded to, without anything in the response being related to the OP, a topic split should be created.
