CoinURL pretty much scammed me (they had a withdrawal limit, I withdrew once I hit that limit and they never sent the money neither did they reply to my e-mails)
Many users have been scammed by them including me, that was one of my worst experiences when I'm just start earning bitcoin.
Same here i have been scammed and my account gets frozen with the BTC on it. CoinURL was supposed to be a good option for this, the truth is we have no a decent shortener service to earn coins, the best option is addfly and buy bitcoin with the profit.
