Good research!
Well imo this is cheating, the "real-name attestation" rule should not be abused by 1 person to create over 100X "real-name attestations" to get a significant advantage on the lottery. Someone should really check the validity of his "real-name attestations" which is obviously fraud.
Anyway the "real-name attestation" rule is somehow designed to abuse it, should be deactivated as soon as possible and replaced by something else if needed.
These attestations are valid. But looks like someone has a huge network of "friends" who are ready to sell their identities for a few bucks. Every distribution method will be abused to some extent.
