...Must be because of the complex name of the account and spammers use easy names to spam...
The complexity of your name has nothing to do with it nor do spammers have "preferred" naming conventions. What matters is your habbits online. If you fill out forms on the net, such as contests and other useless ****, then get ready. The SPAM is comin! Also, if you post your e-mail address on forums, newsgroups, bloggers, etc. the same will certainly occur. One annoying factor is companies that end up releasing your information. This happens more than any of us would like to believe. There was a scam (can't remember how long ago) that went something like this:

1) You sign up for their service and the agreement had all kinds of protection for your personal info.
2) Suddenly there was a buyout by a company who has no protection for personal data
3) Your data gets sold for phat bling to whoever pays up
4) The cycle repeats

Anyway, the point is that spammers use all kinds of dastardly methods to collect addresses. They don't discriminate based on your e-mail address complexity.
