MyLikes is sneaky with how they do shit. I'd suggest opening different mylikes accounts for each twitter page you have.
I've had instances where I've had like 5-10 accounts promoting the same link. I'd be happy as hell to see (for example) $100 made on one advertisement with like 10,000 clicks. I'll refresh my earnings hours later to see I'm down to like $20 from $100 because they removed the clicks gained from the other accounts. And yes, sometimes they'll even ban you.
