They are so easy to spot its kind of pathetic.
Yes for some of us. But we have to know there are some noobs that come here daily looking to get rich quick. Boy are they in for a surprise.

IMHO these scammers do some positive work. People should learn - and they mostly learn on their own mistakes.
Some people store coins on exchanges/web wallets - sooner or later they will learn not to do that.
Other people don't have backups/keys of their wallets - sooner or later they will learn not to do that.
Some other noobs use such obvious "steal you coins" miners - actually a quick way to learn.
It's a natural selection.
