No guilt here
And you probably wouldn't want to hear what else I have done to El Reg with Grease Monkey scripts after you changed your format such that it wasn't how I wanted it. In for a penny, in for a pound, so everything I don't want is stripped out. Then I have An Ad Blocker on top.
I'm actually not that adverse to adverts, but there's more to it than that; they are a vector for malware, spying, snooping, and, above all, are often the cause for slowness of site loads. I got so sick of page loads stalling on adverts that I reached for the nearest hammer. Other tools may be available but the hammer works for me.
As for sites which block me from visiting because I Ad Block, that's their loss not mine. I just ignore them as if they never existed in the first place. I don't think there's been any time I haven't found what I was after somewhere else.
The question advertisers should be asking themselves is; how did we piss off so many reasonable people?
