Gab has been throughly banned throughout most of the fediverse because of the constant spew of abuse. I don't believe that truth.social federates but I see it a lot in blocklists. Some people will automatically block people using the Gab fork of Mastodon as a last ditch attempt to curb hate and spam.

This is kind of the nature of the beast. If the problem is that the remote instance allows things that you find intolerable, then you have to ban the remote instance from federating with you. Speech may be free, but actions have consequences.
