coming from a super long time mmominion user, are you sure you didn't mention anything to a friend regarding either a parser, bot, or any 3rd party tool in game chat, cause i haven't been suspended ever for using minion, however i have been for swearing in chat, a suspension usually requires first a complaint to start up an investigation on your account by SE.
Only other thing i can think of is someone maybe hates you on the server and saw you crafting in the same spot for 2hrs+ straight which is why i craft in remote area's, cause i feel that you were 99% reported to get that suspension, all it would have took was for SE to see you repairing your gear in the same spot without going to a repair NPC, however you would have had to have been reported for SE to even start the investigation.
Edit: and when i say i've been using it for a long time i mean since 2013 (not that specific addon but once again seeing what that addon does i doubt that was the cause).
