I first found out about Heyuri around 2021, when kuz posted about KolymaBBS on 4-ch. I think this was around the same time there was an Ayashii clone and other textboards that almost immediately died, so I didn't bother with posting much. I wasn't all that interested in imageboards at that time so I only started actively posting on Heyuri recently, around like the start of this year. Apparently, I missed quite a lot, looking at the wiki
