I have recently noticed an increase in the number of players (some new, some not so new) being asked for their password ("Give me your password and I'll do those quests that you can't do"), and then, 10 minutes after giving away their password, said player is back online complaining that they got ripped off and their account has been stripped of oddies, and even worse...

"they didn't even do the quests"
These scammers then use the compromised accounts in order to target other players, so if you've foolishly given them your password, you need to contact Oddlabs immediately and change it so your account doesn't get used for this nefarious purpose.
If this has happened to you, please post the name of the person who scammed you so others are aware of it. Then go hide your face in shame for letting yourself get sucked in so badly
Most of these compromised accounts can be traced back to 4 culprits: Oyster, Baseball, and El Master & his brother Counter
I'll try to edit this post as new names are discovered.
