Not really, though. Devs have asked people not to use them for harassment, but they've never really said that they would cause more - that's just something the community decided. This source is a bit old (
https://www.youtube.com/watch?v=3-WX...outu.be&t=6m5s) but he never even mentions harassment as one of the reasons, let alone the foremost. Here's another interview (
http://gamerescape.com/2014/02/12/ps...naoki-yoshida/) where yoshi's asked about it and never mentions harassment in a 3 paragraph answer. If your argument is that it's a dev position, then you should really have a source. In this case, that's not the dev position, it's a community position.
I know everyone says it's a dev position, but it's really bugging me because it's really not true at all. After the first ZAM interview where he laid down fight club rules, everyone started saying stuff like "so basically as long as you don't use it to harass people, no one will know." Which is true. But that was just because harassment would break the fight club rules; harassment itself was never the focus until the community made it that way. Harassment being in any way relevant to parsers was a conclusion drawn by the community via a series of implications, none of which are really tied to any dev statement.
At this point everyone just assumes it's true because so many people say it, and people say it because they assume it's true, and they assume it's true... ad infinitum. That argument might trump all others if it were true, but it's not.
As for your personal opinions about it... where are you gathering this evidence? Everything I've seen and experienced personally (stuff like this
https://www.youtube.com/watch?v=GFWh9aY4pas) suggests the opposite. If you're going to appeal to history, can you find any examples? I agree that there's no reason to think history wouldn't repeat itself, but we apparently have very different ideas as to what that means.
