If you've recently received a Private Message which you believe contains a suspicious subject (to look at something, a new YouTube, etc.), DON'T OPEN IT! If you're unsure and still want to check, please resize the browser window to a small size and slowly scroll through the content for verification.
There's about 6 accounts known for sending them, but mods/admins suspect they've been hacked. For now, they've been permabanned to stop the PMs and an e-mail was sent to the account owners letting them know what happened.
Please let me (or other mods/admins) know if it still continues. Thanks, and I apologize to those who have already been exposed to the PM's contents.
