I banned them using the spam cleaner, but they still show up in the members list (at the top since there are no other users yet!!), and what is worse, the Recent Activity list shows them setting a link to their home page (which, because they are a spammer, is a spam link). The following screenshots are from a non-logged in user.
Also, clicking on their profile shows their signature, completely with spam links!!
This is a serious problem that needs to be addressed by the core software - if a spam user is banned, we need to remove all reference to that user - especially their home page and signature from their profile that contain the spam links!!
This is not just a regular user who has been banned - this is a spam user and as such, all traces of them need to be removed to discourage further spamming.
I realise that these links are all nofollow, so there is little (or no) search engine benefit to be had - but the fact that these clearly spam links are still visible to my other users lowers the tone of the site and may spook new members.
I believe this is a flaw in the spam cleaner.
