I wonder why they picked little old me? I wonder if I should actually be flattered.

They might want to use your Legendary status to get more stakes. Rest assured, any decent manager would know that 'reputable members' won't spend their time bounty hunting or using altcoin sig which is not guaranteed when they'll get paid.
Well I have a history of getting involved in plenty of shitcoins.

I still am active in a couple. However, most of these bounties are involved in shit tokens. I have been loath to get involved in tokens since the Dao burned me. My butt still hurts bad from that one.
