I have a lab at home and do host some stuff for myself from there in a small DMZ (ie: Miniflux RSS readers, Plex through Reverse proxy etc).
But I used a linode for my lemmy/kbin stuff. Reason being is that the code is fairly new and there may be exploits bugs and
I dont want to deal with my ISP made an instance is exploited and becomes some type of C2 box or spews out spam. Kbin specifically already has PRs to fix XSS and Sql injection stuff, the former of which is usually avoidable if you just follow some pretty basic principles. So its a concern.
Linode has better bandwidth than my non-symmetrical ISP uplink and is on its own quota.
