I saw someone comment under @theycallmedan post about this how the voting relies on a simple browser cookie mechanism, and he was going to go off on this 'exploit'
I'm sure some 'double voting' did occur... but what can you expect... make your system to be okay with than and? On a hacker site of all things...
I didn't realize their mechanism was cookie based.. Perhaps @theycallmedan has extra info on this and if it was him..?
I don't think it was him, he made a new post saying he was going to email them asking if they could subtract the fake votes to get rid of that big red message on their page... so I don't think it was him. Probably a few people did this thinking they'd be doing steem(it) a favour but now it just doesn't look all that amazing - not that they had any way of knowing. If you have a system that can be gamed, people are going to game it...
