When you host your own Lemmy instance that means every server ypu federate with is going to copy its dataz including images to your server. That means that if you federate with someone who is poorly moderated, you can end up hosting CSAM yourself. You need to be prepared to deal with that problem.

I did it for awhile but didn’t want to deal with the CSAM. Shut it down after a few weeks.

The only thing that sucks about it is some sites just flat out don’t work well. For example, in Librewolf I cannot login to my banks website. The site loads, but the login just hangs. Firefox it works immediately.
