1. what evidence supports that sopa was not a reasonable way of combating internet piracy?

The fact that it could perfectly be used to censor free speech by using copyright provisions as a pretext. Such censorship can be political or commercial or both. Indeed, it has already happened, as in the case of Oliver Hotham, a British student journalist who in 2013 interviewed an anti-gay group and posted the video of the interview on his blog. The antigay group did not like the negative public reaction to such exposure and used American copyright laws to demand that Hotham removes the video from his webpage because they “owned their answers to the interview” and Hotham had to right to post them without their permission. SOPA included and expanded such over-encompassing copyright restrictions and would have facilitated such abuses. They threatened Hotham with litigation unless he complied.
