I've seen rate for rate spamming ruin the scoring of jams in the past, and I'd like to see a fair and honest jam here.
It's alright to ask someone to play your game if you've played, rated, and gave feedback to their game. But blanket "rate for rate" callouts can really mess with ratings as people try to collect as many ratings as they can without playing/having their own game played.
If I find people posting blanket "rate for rate" posts here, they will be removed. If I find too much of that happening, the community tab will be removed entirely.
