Repl talk has a lot of spam. You get empty joke posts, or just posts that people put no effort into and share anyway. That's why I am suggesting peer review. Each post that was made would first have to be reviewed by two community members or one moderator. Once it has been reviewed, if the review was positive, the post will automatically move to the share board. If the review was negative, the user will get a private notification explaining the reviewer's motives for the negative review. This could help curb spam, and also improve the quality of posts in general.
