This is less a bug and more using a sort of "back door" to get to profiles you normally wouldn't have access to. As far as I know, and I may be wrong, there really isn't anything we can do about it.I am strangely able to follow any perma-banned member. Not sure if this is a bug, or if anything can or should be done about it, but you can look at any warning ever issued, even on restricted or banned profiles. This can be done via the URL: https://forums.terraria.org/index.php?warnings/ followed by the warning number. I've used this in the past to bug out my "Following" list, where it says I'm following over 100 people, but only 6 show, as all other members have been banned prior to following them, whether they be a spambot, troll, duplicate account, or what have you. Warnings for deleted accounts won't show this way, but I have not tested to see if it's possible to follow a deleted account or what happens when a member you're following gets deleted.
I'm unsure what happens in regards to a deleted account. Maybe I'll run some tests on the next spambot that slips through the cracks.
