I noticed that recently i have received many free tokens in my TRON account. After some investigation i have realized that it is an attemp to steal your TRX. 

They are actually SCAM sites that are using pseudo-contracts claiming a generous airdrop in TRX. 

They use well-known crypto names for their tokens such as ADA, DASH, ZEC, FIL, etc

Always check token info. for example the following image is the info of a fake "DASH" TOKEN

when you are connecting to their contract they are claiming that you are the "lucky" guy and they offer a swap for their free tokens with Trx. They asked you to connect your wallet and sign the transaction. 

for example if you follow in the above example the token url you will be asked first  to connect your wallet as in the following image

Be CAREFULL. After connecting they know your balance and after signing you are actually transfering them your valuable assets and you are loosing them forever. 

Always make some search about curious tokens coming from nowhere in your account claiming that are gifts or generous airdrops. Check for "token name scam" every time. 

Unfortunately scammers are around us and trying to steal our valuable assets. 

Hope that this article will help you to avoid some cheaters and save your assets :) 

P. S. Leave a comment for any TRON SCAM Tokens you know.
