I've seen plenty of RPs asking for one post a week. Hell, I ask for it myself unless I'm inspired to write more after my partner or players/fellow RPers posted. I've even been in RPs where it has taken months for posts to roll in, too.That could be true, however I disagree. If you can only post once a week, then that could mean you're waiting for that one moment of escape... Why label posters like that.
Anyway, considering I have a RP career that spans more than a decade with thousands of forum posts (almost 6k on one forum, for instance) and have countless hours in weekend tabletop sessions (12.5k hours currently on roll20) dedicated to RPs that have lasted literal years even with that requirement, saying that someone shouldn't RP because they can only post once a week is absolutely moronic. I know calling it moronic sounds harsh (especially since this is an "unpopular opinion" thread) but since I'm pretty much living proof of the opposite of what was said and have seen proof of it working in other rps that I am not in, I honestly can't agree with their take.
