Some players are spamming messages giving a link to a website promising clintz, cards and credits.
On this site, people are asked to give their user name and password first.
This kind of sites are ALWAYS created to scam players and steal their password.
If you try to use this kind of sites, you will never get free cards. It's a lie !!
Your own cards will just be stolen few hours after you gave your password.
NEVER give your password to anybody.
