It’s honestly USUALLY not that difficult to dedicate sufficient time to prune a community here as needed within reasons. Beside a well moderated community is less likely to be spammed in the long run considering it will be less efforts than it’s worth.

Problems USUALLY arises because there’s a lack of moderation, not because new users should be pulled back or from being signed up. This is more evident in game servers and believe me I can tell them apart what’s a well oiled game server from one that isn’t. Same goes for online communities.
