I have been using ySense on and off for I believe a year or so. I would only really finish surveys and offers that seemed somewhat profitable, so I wasn't a very active user for most of the time and I did not really have many complaints.
It is difficult, however, to give the site more than 1 star, as my account has recently been deactivated (which I found out by trying to log in, rather than receiving any sort of e-mail). Luckily, I only had around 10$ on there, as I had been cashing out whenever I reached the PayPal threshold. Now, deactivation wouldn't be a problem - perhaps I've done something wrong.
Here is where the absolute worst happened - I tried to contact customer service, asking what I've done wrong - either to explain myself or simply understand what even happened. The answer was a copy-paste "you violated ToS", which is okay at first, so I tried to dig deeper - after all, I had some small amount on my account and I didn't believe I've done anything wrong. The answer to my followup was "noncompliance with ToS". Not only that, they also finished the e-mail with "case closed, the decision is final".
In other words, they deactivated an account with money in it without giving a single reason and then decided to spit in my face - good going, ySense. Do not use this website, because you never know when they're in the mood to simply close your account and lock all your funds.
This is not Ysense. This is a review for ClixSense and we went out of business years ago. Get it straight!
