You have to accept the fact there there is bound to be something bad among community-made content (on CG or other similar websites), as (a) all approvers are volunteers and cannot dedicate all their time and effort on moderation, and (b) some approvers/creators just don’t do a decent job… But let’s be fair, not all the clashes are that bad. Some are actually quite good.
You can help moderate clashes too, if you have the time.
Remember to downvote bad clashes; a bad enough rating disables bad game modes or even the whole clash.
I’m requesting CG to include a freeze-period to avoid rushed approvals, and if they agree to that, hopefully the situation will improve a bit.
