We see that people have been gaming the account creation and rep system for byteball airdrops for accounts of 30 and 40 rep.
Byteball has put out a mechanism to thwart this.

Here is an example of the method that was published by a steemian on the net of how to Rape the Airdrop

We do however have another set of abuses of the Airdrop happening and this relates to the referral rewards. I've been able to replicate the process, another attestation fee amount is sent to the new account just before the attestation fee is paid. This results in the referral reward being sent to the sender of the second transaction.
This is the address of the sender:

and as we can see they have been pretty successful:
