@gordoooo_z Never too late to make a backup of your follows and followers, most Fedi software allows you do do it in account preferences unless configured not to.
I have my own single user instance, but it's hosted on an old MacMini and I don't put too much trust in that thing — if it breaks, I doubt I'll be able to find parts for it even DDR1 desktop RAM and 2,5" IDE HDDs are a rarity these days, everything else — even more so.
That is why this one remains my main account.
