My thinking on Limit vs. Suspend:
Limit does almost nothing to prevent interconnections between the two servers, mostly only changing the aesthetic experience of Fedi users. In particular allows Threads.net users would still be able to follow social.coop users who haven't set up following by permission only, and thereby give Threads.net access to followers-only posts and other locked information. Thus Limit requires positive action by users wishing to protect themselves.

My concern here isn't bots and sock puppets, but real users that we might actually want to interact with, but who happen to be on surveillance platforms.
