You know what's ironic in this unpleasant situation? Coolserver.host has posted something like a guide on how to recognize, stay safe and not get ripped off just two days prior to him scamming. Let me quote:
I hope this helps a few people not getting scammed on the forum.
I don't know if ultimately his intention was to trick and scam someone or he just saw an opportunity and took advantage of it ...not that it matters and should excuse him for what he did though.
Other than that, I fully support vit05's suggestion and would post under any wallet-related seeking help topics, that you should never under no circumstances accept any help in private messages from low-ranked members:
any bug-related issues about wallets problems should be addressed in public posts. There is no real gain for this conversation to be private. Since the solution to the problem can help several other users later.
