That sucks, sorry to hear this and also sorry that we will always have people like this involved in this world, especially in the altcoin arena.
I have seen a few people claiming similar things, as long as everyone is vigilant we can hopefully starve these parasites.
i agree that we should find a way to starve these damn thieves . im not exactly sure how it could be done but its about time to actually start some kind of control to put these guys out of business.
and yes to run all the needed precautions is a real pain in the butt but sandboxing every single one is also a punch in the head at times!
and yes this will always be part of this world!
