While it seems most can be bypass through one means or another, some of my regular websites completely stripped their homepage of everything. So yes, there several that have completely unavailable services.
I can't speak for everyone, but the ones that use the FULL PAGE BLACK SCREENS are impossible for me to ignore, so adding a tiny (click here to continue) wouldn't be a total disservice, I don't think.
I am completely against SOPA/PIPA, but I feel the same amount of awareness would have been raised if pages like
Strike Against SOPA & PIPA had a tiny link or something to bypass the banner. You think congress really gives a damn if Wikipedia goes black for a day? The people that are being hurt the most by these blackouts are the ones that couldn't put their hands on a congressman if their lives depended on it. The big companies raising the awareness are, with their lobbyists and finances. I would stake my life that if this bill somehow only impacted individuals but not the big internet companies, the awareness would have never been raised. And the secret society known as congress would have gotten away without much public knowledge until it was too late.
Also, who is C@$e0 (C@$e0?)
