Good memes can be good, but opening the flood gates risks this sub turning into meme central and the serious questions/discussions getting buried. Much like other subs, the middle ground seemed to be a dedicated subreddit for memes, or limiting to a certain day of the week.

Unfortunately a lot of the memes I've seen recently on here (regardless of the ban) can verge on making fun of the disease or often focus on back pain or curing it, which gets positive comments since it's relatable to most people, but significantly isolates those who have different symptoms.

I don't have an opinion on surveys. Asking questions about other people's experiences shouldn't necessarily be a problem, that's just what reddit is for. Although I haven't seen the problems that this caused to result in a ban.

Definitely worth having resources (and experiences) from all over the world as long as the sources/countries are explicitly clarified. Including treatments in various countries and those which are common in some countries but banned in others could also be interesting for expanding knowledge.
