Cryptotab: Scam or not?

Is Cryptotab a Scam? I have a lot of questions since my CryptoTab account was blocked, so I asked them for a reason. I haven't received any more replies from them, detailing why was my account suspended, so with this occasion I did remove the invite links and consider them at least suspicious. Is it CryptoTab scam or not? I'll let you judge this, but I did search myself for this question and got a lot of interesting reviews on other websites such as TrustPilot where they have a rating of 1.7 out of 5, with most users complaining that they don't payout anymore.

CryptoTab Halloween candy hunt with crypto prizes

A while back I started researching crypto mining apps for Android and CryptoTab was the first one I've started toying with. It's been a few weeks and I already got the huge amount of... $1 :). Hey, at least it's money I'm bringing in, not giving out. Anyway, I almost forgot about them but I received today news that they're organizing a Halloween competition where you can win in the end crypto by hunting for candies. You can enter the competition here: CryptoTab Halloween competition.
