Revenge is profitable on Steem?

Just read a memo sent to me:

Transfer 0.001 SBD from kaaser

"Someone has downvote you? Do you want to revenge? I represent service of downvote. Send 2 SBD or STEEM to @kaaser, and we for you will revenge. Downvote will be made from three accounts with reputation 72, 69, 65 and with a general force of 480.000 SP. For anonymity, send URL of the account which needs to be downvote on mail - [email protected] + your name from which you have sent SBD or STEEM".

Honestly.. why would you spend money for revenge on Steemit. I mean I get it.. somone took away your rewards.. so you reward them by losing even more SBD (And they have no idea where the "revenge" came from).

Seen it all now.
