The Darwin Awards - long a favorite read, for me.
Found you because of @hugewhale (yes, I paid the 0.700 SBD; call me an idiot). I see another offer in your reply section, Send 0.001-0.008 SBD/STEEM + url->memo to @thegoldencobra for an upvote!
Sounds sketchy to me.
And all these "I upvoted you, now please upvote me" - usually it's from some newbie whose vote is worth a fraction of yours. Plus it's bad manners (in very poor taste).
