I think hilariouschaos (or lemmy.today as it too has a “serious” conservatve community) are the ones you’re referring to. I too was confused initially.

Crazypeople.online is the successor to wallgarden.xyz and its main communities are the eternalplaylist and the weed ones.

PS. Their name reminds me explodingheads for some reason, which is similar to hilariouschaos (and I think theyre shut down now).
