I think the question about visitors to the site being blocked by certain words in thread titles is a red herring. Why are they being blocked? It seems to me there are two possibilities:

The first is that the content settings in your browser or security software on your own PC are blocking the site. The solution is simple - change the settings.

The other is that the site is blocked by restrictions set by your employer on a PC at work. However in most companies private browsing is not allowed, or at least is strictly controlled. Again, the answer is simple - you probably shouldn't be looking at Mudcat at work in the first place, so accept the restrictions and wait until you get home.

Neither situation is a good reason to change the policy.
