I don't think the intention is to suspend ElonJet since Musk has already explicitly said he made the choice to not suspend it despite the alleged "personal safety risk". Trolls in this case probably refers to accounts that paid for new Twitter Blue and are now impersonating well-known figures/entities.

The wording seems consistent with everything going on at Twitter so far, that he's just kinda winging it while everyone else is frozen in confusion over the abrupt changes. A $44B acquisition is quickly reverting into the volatility of a 2006 startup.
