In the thread How do I track down the cause of a StackOverflowException in .NET?, I find that George Stocker has made several edits to the question, removing hundreds of characters, in addition to editing just about every answer.
Yes, the OP does not have strong English skills and I believe George was just trying to make the question clearer, but this seems excessive to me. Moreover, the OP has complained that items he felt were relevant have been edited out.
I consider this improper use of the edit feature. Yet, I have no way to contact George, or to flag, report or otherwise try and fix this. Yes, I can revert but then I'd lose some more recent edits made by the OP.
Shouldn't there be some way to moderate the way people edit posts?
