Site blocking can be circumvented by BugMeNot users by publishing usernames and passwords under a similar, but different, domain name to which they apply.

For example, the owners of the domain abc.def.com might request a block to be put in place, but this will not prevent users uploading access information under the name of def.abc.com.

The operators of BugMeNot expanded the "MeNot" network in October 2006 with the addition of RetailMeNot – a service for finding and sharing online coupon codes.
