I mean it’s no rules. You can post 1000 threads but that’s not good practice. first thing I would say is don’t spam the feed.
Look at it like this, if u came here for the 1st time and u saw 1 profile posting stuff back to back u might assume it’s a ghost town or if you’re already user, it’s just irritating to see and won’t get much upvotes if any.
5-10 over the course of a day is more than enough. Comments it’s whatever though because they don’t show on the main feed
