I was interested in Free Crystals for Star Wars Galaxy of Heroes SWGOH. But the user has to pay real money before they can test this. I can't judge whether it actually works. After entering my google play email address, I was asked to enter a verification code. To get the code, I pressed a download button. There was no download, but another website opened. To activate that new website, I was asked to complete an offer from a list, which had only 1 entry (hot videos). I clicked on the link and was referred to an erotic video website. They knew my real phone number (I was using mobile hotspot from my cellphone). They offered subscriptions for daily or weekly cost. One more click and I would have paid actual money. There was no free offer. I closed all the websites. I tried to post my experience on their website. After posting a comment, this comment was subject to approval by fragcheats.com. I am sure the comment will never be posted because it was critical. All comments under their offer are positive. No surprise as they can block all other comments. My conclusion is, they collect real money and are unlikey to give anything back.
