I’ve got this exact problem too with the type of gmail accounts mentioned above. Trouble is, I am an admin of a forum without any FTP access (the designer went AWOL) so I have no way of installing plugins to the directory.
As a temporary measure, I have used the already-installed Register Plus plugin to enforce admin authorisation of every new member.
Yet despite implementing it last night, spammers are still able to register and post. Anyone know why this might be? The plugin is listed as active.
