Is it possible to post 50,000 without being called a troll?

Yes, troll is about how and why you post what you post not how much. You can be a troll with one posts if the purpose of your post is only to pick a online fight and stir the pot. That is not to say you can't have opposing views but it is why.

It depends what you post. It's the [i]content[/i] of one's posts, not the [i]amount[/i] of them, that makes one a troll.
