This will always be a risk in a federated network. You need to find reasons to trust the node you join (I know some of the people running the one I chose) and you should arm yourself with malware defence - both of which also applied to old Twitter and even more so in Musk-owned Twitter because there's already evidence he's abusing it.

Most of the comments on that tweet are depressing in their ignorance. They blindly went in one direction and are now blindly fleeing in others.
