Hello!

I noticed that I received one TRX today from a wallet address belonging to SmartGamesIO.. and I have no idea why?!  I have not voted for them or anything so it's not voter rewards for SR or anything.  I mean, I am not complaining about free coin, as a faucet grinder I appreciate any penny of a penny earned, but I was just curious how or why it was received? I've not heard about SmartGamesIO until now, so not involved with anything with them as far as I know?
