Yeah, so um. Straight to the point: don't give out your username and password.

You know, some people guarantee you a free membership account, but they tell you they need your username and password? Well, don't believe them, because your account will end up getting banned or hacked. Maybe they might use your ecoins, too. So, don't trust anything that requires your username and password. If you really want to try it, just use a fake account, but not your real one.

I personally don't think there's cheats for a free membership or free ecoins, unless you do offers on the actual site. It's either you pay for the membership or don't get it at all. There might be websites that makes you earn "points" to get a free membership and all, but it's.. Tedious.
