All the big accounts that already get zapped tons lining up like this can be annoying. It is within my power to block and unfollow and I'll never see that person again. Very different from other sites where I don't get a say.
To be clear, I think zapvertisers should find smaller accounts that already posted about their product. Then hit them with the zap, boost, comment trifecta. More beneficial to everyone involved that way.
