Yeah, the scams are always a huge problem, especially when the value goes up or popularity suddenly increases.
Fortunately, dapps like keychain are making things much safer. But, if you willingly send someone Steem...hopefully, you have sympathetic friends.

I see the potential for more scams when SMTs arrive. For a few Steem, anyone will be able to make an SMT and promise the world to their 'investors', lol.
