LinkingLion: An entity linking Bitcoin transactions to IPs? https://b10c.me/observations/06-linkinglion/
An entity active since 2018 and on a Monero banlist, is opening connections to many clearnet Bitcoin nodes, probably attempting to link public node IP's to transactions.
Interesting to see how ChainAnalysis companies are attempting to be involved in the network while analyzing transaction data to build/link heuristics.
