Like, I understand that these people are upset, and I've said stupid shit when I've been angry, but really, this is a petition to try to change something. Use a little bit more eloquence, and back up your arguments with data. Like, if they're talking about voat.co, are they really trying to insinuate that Voat gets nearly as many views as Reddit? And, wasn't Ellen Pao already interim CEO before the trial concluded?
100,000 + signatures should still count for something, and I imagine anyone with a vested interest could do a little investigative work to understand what's really going on.
The sheer amount of natural language written about the topic on reddit and elsewhere should tell you how many people are interested in the subject of reddit's management.
The petition was started some three weeks ago, but the number of signees hovered around 10,000 until the last few days. Also, over the last few days the number has risen at a consistent pace.
I assume change.org has some filter in place to attempt to achieve uniqueness. Regardless, the problem you're describing is a function of voting on the internet, not any particular community. Given interest and opportunity, there are individuals in any community that would try to rig the system. For example, competitions shared on Facebook, or even whole countries.
Remember when the genius sleuths of reddit wrongly accused an innocent man of the Boston Marathon bombing? Or all the ridiculously borderline illegal subreddits (jailbait, creepshots) Hell, there's an entire wikipedia article devoted to redditor drama: https://en.wikipedia.org/wiki/Controversial_Reddit_communiti...
To be fair the reasons you stated have been discussed endlessly on reddit.
I agree that petition could have been written better though. I didn't even think to read the description until you mentioned it. I doubt many others have either, they just read the headline (as usual...)
