Sorry for the late response. Life's been hecktic, but sure.
1: Pretty sure you know this already, but NEVER EVER...EVER give your password to anyone to asks for it. The admins and moderators here do not need our passwords whats-so-ever. The only time we REALLY need to use it is when we, obviously, log in to play, buying/putting stuff on the MP, applying to be a mod, etc. Anybody who asks for your password in a post/PM/comment/flash-space must be reported spot on for password phishing.
2: Don't click on weird links! Anybody who sends you a weird link and always has something on the sidelines like "FREE RARE STUFF", do NOT fall for it. You will NOT get an angelic halo, nightmare scarf, or any other super rare item. Those links are phishing links made by hackers, and are designed to steal your account. Remember, the URL for Gaiaonline will ALWAYS be www.gaiaonline.com. Anything else that LOOKS like Gaia, but has a weird looking URL is a phishing site, and whoever sent you the link to the site must be reported for password phishing. (Note that if you do end up falling for the link, QUICKLY change your password.)
3: Some hackers exploit glitches to get into accounts, such as making pop-up adds that will ask for your Gaia username and password. Do not enter your information into the boxes, obviously! Close the ad, copy the URL the pop-up popped up on you, and...well, depending on where you find this bad pop-up, Go here to see the different methods of reporting it, depending on where you find it.
4: There is a new phishing method on the loose, where hackers use a site called "Join.me", a screen sharing site. In the message they will promise "free items/gold". DON'T FALL FOR IT! Just close out of the link and report the message the user sent as password phishing.
5: Hackers also use this method where you trade session ID's, and the ID basically allows for hackers to mess up your account! Check Here also, to see what these naughty hackers do.
Aaand that basically wraps it up.
Oh, and tip. Hackers sometime ban the hacked account so the original user can't use it again. Note that you weren't unfairly banned, blame that darn hacker! If this does happen, file a ticket, via topic "banned due to hacker's actions". Afterwhich, you will be successfully recovered.
Also note that all reports and tickets are handled at a "first come, first serve" order.
