This has turned into wargames or something.
I have often in the past had trouble getting onto doughtyuk.net, no idea why. I ended up changing my proxy server in the browser settings and was able to get there fine. Seems to work alright now.
I once had an email from someone who couldnt get on my website- apparently some kid-friendly filter was working on their end to block my site.
I emailed the software company and had a go at them asking why my site was blocked in their list of evil websites.. I was a bit embarrased when he pointed out my meta tags (hidden keywords) on my homepage had all sorts of mad random words like "porn", oh yeah, I remember doing that!
