As soon as Facebook disabled their email feature, I started getting spam mail from IMVU to my personal email account. The first few messages I disregarded, until I realized that I was receiving messages and friend requests. I have NEVER signed up for an IMVU account (not something I would ever be interested in) so I knew my email address was being fraudulently used.
I contacted IMVU, which was also another load of crap because in order to contact them you have to create an account or create a ticket. I received a prompt reply, much to my surprise. They stated I had to email them from my Facebook email in order to delete the account. Well, bad news Facebook has permanently disabled email access, so I am unable to send an email.
IMVU has a ridiculous customer service policy to only side with the user who has stolen someone's email address to chat with other avatars. They take themselves a little too seriously. I am currently awaiting a response from IMVU to find out how the account should be deleted. I have a feeling they will be unable to resolve the matter because they have horrible policies. Seems like one big scam to me. Stay away!
