The one problem is I like to use private browsing because before I did, my browser would get filled up with a ton of crap in my cookies and history. but it was hard to clear out only the crap but still keep the stuff I needed. I use regular mode for Mturk since it's not as spammy, but the other sites get pretty bad. I just noticed with Cashcrate, the types of offers they offer are the ones that are less likely to credit compared to other more reliable sites I've used like Swagbucks (and of course Mturk -- I rarely get rejected for a survey on here, where as many other sites, I'll spend fifteen minutes answering questions only to find out I'm disqualified and I earn a penny).
