I can confirm they are scammers, but of course scammers like them not fool, they only scam some people, so that the others which are not scammed can give review like this; microworkers.com is legit and so on.
3 weeks ago I paid them to run a campaign on that ### ### website..they deduct my banking balance, ok no problem. Then after 3 days the campaign still doesn't run, instead they deduct again my banking money without my agreement, simply like that, before emailing me telling me I need to tell them the exact money they deduct otherwise they will void my transaction in 5 days, WTF! Didn't they know the exact amount of the deduction since they deduct my money in bank? With this point, I 99% confident they are scammers, brilliant one. Why not before I made payment, state that they are gonna charge me again for the verification process, why not? And WTF don't know the amount that they deducted and asking me to tell? Because they are scammers.
But I still have 1% faith left, so then I go to support and tell them the exact amount like they ask me to. THEN until now they don't run my campaign and even respond to me! Then Here I 100% confident that they are brilliant scammers. Avoid this microshit at all cost! I wish I could research before I made decision to pay them for the campaign, coz WTF website like that, asking people, i.e. pay people to cheat click google ads, and other illegal things is supposed to be a good legit site. AVOID AT ALL COST, ESPECIALLY IF YOU WANT TO PAY THEM FOR RUNNING CAMPAIGN!
