Hi Lynn,
I notice in the memberlist that there are a lot of members with no posts and suspicious websites. These are usually signups either done by "bots" or humans that get paid to do it.
There is a MOD that will make cleaning this up very quick and simple.
Screenshot of the admin panel:
The original version of this MOD is way out of date and will not work with
the latest versions of phpbb. However, I have updated it and have a copy if you are interested.
let me know,
robert
