If it is not obvious, repl.it has a severe lack of moderation. The repl.it talk boards are full of trolls and spammers and that quite frankly hurts the reputation of this otherwise lovely site.
I'm sure that the repl.it team is quite aware of this issue, but I have not noticed a decrease in troll posts and general spam. In fact, levels actually seem to be increasing.
My suggestion is to employ more staff. I'm sure there are many trustworthy members on repl.it who would voluntarily moderate repl.it. That includes myself. Please, repl.it team, please increase moderation on repl.it talk.
This issue will not solve itself, and I am merely providing my opinion on a possible solution.
Although I have been using repl.it for a few months now, I only recently checked out their community pages on repl.it talk. And this is something that I have observed myself.
Apart from this, I have also noticed how an extremely large majority of the posts on the share board are about people building some game. Is there some correlation? Nevertheless, I think repl.it talk could be a lot more interesting if there was more diversity in the projects that people are sharing.
