Neon - how is this spam? Is the same user posting a picture thread three different times? If not, then anyone posting a "Goodbye" thread is spamming too. There are more of those than picture threads.
They are. There's personal and global spam. Either way, we've posted reasons as to why posting pictures is not allowed. Those of us with forum access on the computer can access any personal information from your Photobucket, including your name and address if supplied, email, and a slew of personal pictures from your albums. This makes posting pictures extremely unsafe. If you'll read Royale's guide on such, you'd note that it was deemed a safety risk months ago. Just like sharing third party contact information, while your intentions may be good, you're potentially becoming a risk to yourself.
Guys if you feel need to post pictures of yourself then do so on the thread created by a player named Unspokenlyhappy. That's a popular thread that keeps all the pics in one place. Locking this in order to keep forums tidy and to ease navigation for players looking to access picture threads.
