A lot of people seem to have forgotten (or maybe just weren’t around at the time) but there were tons of duplicate communities on reddit during the first years too. Over time their mods either agreed to close one and point everyone to the other or the less active ones faded away naturally.
One problematic scenario I can envision with that approach on Lemmy however is the mods of news@lemmysite1 and news@lemmysite2 agreeing to keep the first one alive, but then after a while lemmysite1 closes for whatever reason. So we’re left with news@lemmysite2 which is a ghost town. Probably not a big deal for a news community, but for something with a lot of info on a particular topic it’s not really ideal.
Porkbun is awesome. A few months ago I transferred most of my domains from Namecheap to Porkbun and I’ll be transferring the rest soon.
Namecheap are still in my top 3 after Porkbun and Cloudflare though.
