On the off chance that you are not joking (or worse, trolling), that is very much the fault of Ernst, the Kbin.social instance admin, for having abandoned the instance that he created for months at a time and allowing spam to flood the entire Fediverse through that server. He had multiple extenuating circumstances, which he profusely apologized for, but aside from that I don’t blame other instances from defederating with it in the slightest. I also still have an account there, and I too have not been able to access the website in about a year, and I too have blocked the entire instance, bc it was virtually the sole source of all of the spam that I was getting across all of Lemmy.
You can read more about it here: https://pawb.social/post/2658114 (original).
I did not downvote your comment here, but I will say please don’t be so eager to spread misinformation on the Fediverse. I found the above link simply by clicking the circle button and searching for the phrase “Kbin.social”, and I even confirmed that you are able to do so on your instance. Leaving the default sorting options in place, this was the 4th hit and the 1st one that immediately jumps out upon human inspection of the titles as being the most highly relevant.
You will do as you please ofc, and people will learn to ignore / block you as a result if necessary, and only very very rarely someone may attempt to correct you (at least in a gentle manner:-) as I’m trying to do here, and as I would have wanted done for me. But if you correct yourself before speaking, then others don’t have to go to that trouble, and your words will carry more weight. I offer this as food for thought anyway.:-)
Lemmy.World (LW) is a nice place: ~80% of the entire Fediverse is there, and it has some of the best communities and least trouble connecting with those communities of all instances.
On the other hand, using LW goes against the entire spirit of decentralization that is one of the primary hallmarks of the Fediverse. So I definitely agree that you may want to explore some additional options. If you are adamant about being defederated from nothing, some instances to look at include Lemm.ee (the #3 largest instance after LW and lemmynsfw.com, see https://lemmy.fediverse.observer/list for more, and for best results sort by Active Users) or lemmy.today. The #4 instance sh.itjust.works is also quite nice I hear. #6 Hexbear.net is a troll instance and while #5 lemmy.ml pretends to be leftist it is actually tankie (I hate that term as it is pejorative, but they really truly do deny that the Tiananmen Square massacre actually happened, as in that anyone actually died in it, so it does fit). You may want to find a regional instance, like Discuss.Online is in the USA, or a language one like feddit.org is a German/English mix, or a themed one like Lemmy.zip is for “tech, PCs, and gaming”. Pay attention to the uptime stats, that’s an important one for me. Maybe for an app that can grab content in a manner that doesn’t always have to be live it could be less so?
Btw in the future, while I have never heard of that app name, in the webpage UI you can go to Settings -> Import/Export Settings “Import and export your account settings as JSON”. Choose Export, and then wherever you want to set up a new (perhaps an Alt?) account choose Import and give it that file. Messages sent to your old account will not follow you, i.e. there is no way to set up forwarding yet, but at least your community subscriptions and block lists will be transferred. Even if you have to do this once from the web UI, this will definitely affect whatever app you use after that.:-)
Oh wow this is a lot. I should have just made a post about this - maybe I will!?:-P
