Well, if the OP is not active on the ANN thread then that does not mean that the site is a scam. So it is not right to declare any site a scam site unless there are valid proofs of the site scamming people. By the way, this site is down and therefore it cannot scam while being offline

I didn't play there, tbh, and I can't find any accusation against them so it's not fair to call them a scam but, at least, people should avoid them should they come back online and restart their operations. Shutting down their services every now and then without prior notice is not a good sign.
Again for any other site, if it is down, that again does not mean that it will come up to scam. There can be several reasons of being the site is down.
Yes, this is not enough to call them a scam but taking the website down (regardless of the reason) without notifying their customers shows lack of professionalism. How can we trust any project they may run in the future!
