I think that you are very likely wrong that it is not a Network 54 issue.
My forum is showing that posters are coming from mostly one set of IP addresses. Which is a proxy servers IP address.
If I blocked this Proxy server it would prevent me from going to my web site but not on here as I doubt that this is not being done on here.
So it is likely a Network 54 issue. I would like it fixed or a response to my post that is still not posted on here yet!
