Trionworlds account creation does not sanitize gmail accounts for "." in other words trion sees [email protected] as different than [email protected] or [email protected] however gmail sees them all as the same email address. I found this interesting as it allows for multiple accounts to be created yet still connected to the same email and saves in email account creation time....this process could be automated fairly easily to generate 100s-1000s of accounts in minutes for w.e nefarious activities you have in mind.

edit- if anyone is interested ill throw together something to automate the process i guess...
