Or those are the guys that stole the bitcoins from MtGox, as they also have to make "legal" bitcoins out of it somehow.
Huh? Those aren't "open comments" and they certainly aren't put there by the sender. Bitcoin doesn't have transaction comments or transaction messages or whatever. Anyone can label an address on blockchain.info, see https://blockchain.info/tags - those tags then show up everywhere the address appears on blockchain.info
The coins go back to this well known address

Yes - wasn't disagreeing with you, Blockchain.info still have to approve tags based on the reference material:)
