Can I be scammed with tasks?

You should contact MyLot and give all the details. Go here: http://www.mylot.com/o/contactus.aspx and select Other from the dropdown list.

I have a five cents task pending since five months here. The best way to avoid this would be to validate automatically the task after a given period like Microworkers does -- the tasks not rated are validated after 168 hours (7 days) at Microworkers -- ; I am not doing anymore tasks at myLot.

Sign-up tasks are a violation. Admin removes them and often the user loses their account. If you completed a task by that user they would be unable to compensate you if that happened. Avoid the tasks that are a violation in the first place: http://www.mylot.com/o/faq/faq22.aspx#6

If you're careful which tasks you choose, you should be safe. I NEVER do one that asks me to sign up at any other site!!! I pretty much only do the writing tasks offerred by SharonBucks. They don't always pay right away;but, if you're not rejected, you will get paid!!! Sometimes her's are hard to get accepted as it takes accurate work & a GOOD knowledge of the English language. I know there have been times that I thought my work was done accurately, but the task owner did not agree & it was rejected. Those that ask you to sign up at another site are often deleted as they are against the rules. All those people just want you to sign up under them so they get their referral sign-up bonus!!! After you've done several different tasks, you will begin to understand which ones are good tasks & which are taking you to a scam site!!! I've done more than 60 tasks here & only had 1 that didn't pay me. Deep down inside I knew I would never get paid for that one so I wasn't shocked!!!
