There's nothing illegal about it. That's why it's annoying as hell that people waste time on pointless crusades instead of focusing on real solutions.
I think most of us realize that the petitions are pointless (though then again, it takes like 3 seconds to sign it so enough people do it), but how would you suggest we fix this problem? Because although this is legal, pretty much everyone can sense that there's something fishy about it and needs to be changed.
I was thinking about how campaign finance works in how candidates tend to get paid during in elections less so than afterwards, but while people - in Texas in particular - get a lot of cronyist returns on their investments, maybe there is something to be said for in-office donations. Votes and campaign contributions are sunk cost, so you can't threaten with pulling them back, but you might donate to your politicians, once they do something you support, like how some politicians have been staunch opponents of SOPA/PIPA since the start and lead the charge against them.
Rather than just writing them a letter or giving their assistants a phone call, maybe consider donating some money?
The old incentive structure in politics is old to the degree of obsolescence, so maybe microdonations can serve to alter that or at least erode it over time? Think of all the people who've praise Senator Wyden, but haven't donated to him. Maybe that's something that should be considered.
If I could vote, I'd try to do what I could to bring SOPA/PIPA into the next election as a reminder of what they supported an do my best to explain it in plain terms to people, but I'm basically outside the American system, but let's a least not do something ridiculous that will have no effect aside from making one side in politics look like clueless teenagers.
