Ladysolly just told me that when she tried to visit the web site of her bridge club, she was blocked by Vodafone's censorship.
There's probably some way that she can prove that she's over 18 and therefore has sufficient moral fibre to resist the lure of the Devil's Bible.
The real problem, of course, is the poor quality of the censorware that's supposed to protect children. I remember I was once asked to try out some censorware. I installed it on my computer, and just used it normally. But when I tried to buy some nuts and bolts, by visiting screwfix.com. it blocked me. And when I looked at the reason, it didn't like the word "screw" in the web site name.
And Disney. They tried to block me. Getting round their blocker was very easy.

So these blockers are easy to evade, and annoying for bridge players.
