Get any messages from random people asking about a hat?
There is an AOL Instant Messenger bot sending LJ users harmless, but confusing, messages. The bot initiates a conversation then messages are relayed between two users. This is a classic phone prank that has been brought to IM. You can bet the sessions are logged so the bot creator can laugh him/herself sick.Read tithonium's LJ entry
You can easily defeat this schenannigan by restricting all conversations to your buddy list. No one will be able to contact you unless they are on your list.
BTW, if you want to contact me through AIM, MSN, Jabber, or be put on my LJ friend list, then post a request on my LJ entry point
