If they are stupid enough to allow an auto-complete on Eccie website, they deserve to be caught.
If someone is stupid enough to use the same user name from other websites/email that their SO knows about and would recognize, they also deserve to be caught.
If the SO is to the point that she is going to suspect and research based on a random news article, she has probably already googled up/is searching your shit the way it is, and you are getting caught regardless.
Also, I agree with Wakeup that advertising is useful. Brings in more people, which in turn causes ECCIE to become a more viable and attractive website for providers to use, which in turn provides more reviews, more options and more competitive rates for everyone. Plus survival of the site due to ad revenue.
If you are going to use a board for this sort of activity, you may as well make it as useful as possible.
