Pedro has been here for ages. i'd go so far as to call him "verified". I have watched him play many times and have yet to see anything suspicious (just watching for fun or eating). His solid skill level combined with his game style often causes frustration with certain archetypes of players. Sometimes he taunts them too, which doesn't help matters.
...unless he recently started hacking, in which case F YOU PEDRO!!! <-- *just kiddin' dude
As for the vote, people often click yes to be jerks, or because they are noobs, or for any number of reasons that don't depend on whether they think the player is truly cheating. It's not an accurate indicator. That's one of the reasons why only donors can initiate votes. In a completely free vote situation, voting is HEAVILY abused.
