There was at least one episode where you "woke up" after a lengthy period of inactivity and excluded (in your trust list) a number of users who happened to be targets of Quickseller's attacks. That will probably keep raising doubts despite the signed message.

If you're now planning to stick around for a while you should review your trust list as it has a different impact than it used to. If you're planning to go inactive again you should consider clearing the list out.
