But if you require a certain number of posts, people perhaps start to "spam" the forums with "low quality posts" just to increase their posts to be able to talk in discord, which would make SL lose it's shine tbh.

This is the main issue with limitations like this, is this.
The thing is that many of these Discord members is they aren't even members.

It's hard to find a balance with these things.
