I see 3 peers indicating 110 in their subvers out of 122 (on nodes that don't auto-disconnect knots peers due to wasting bandwidth with needless redundant txn fetching). Whats the deal there? The BIP is, of course in a typical show of incompetence, utterly silent on any p2p visibility. There used to be more.
Onion or public IP?
If they are what many of us suspect to be, just sybil attack with many of the nodes just being one node with multiple onion identities or just running a proxy back to one node if they are on real IPs it might be that once one 110 node has a certain node in it's ban / block list it's actually stopping what might be what looks like dozens or hundreds of IPs / onion addresses from talking back to that one blocked node.
