I appreciate the desire to get both sides of the story and not taking a random strangers opinion, but I'm also sensitive to connecting the internet hate machine to anything personally tied to me so I'm going to pass on providing supporting evidence.
Feel free to ignore my anecdote. I know it isn't much good without that connection, but it also isn't good to remain completely silent about bad behavior. Frankly I don't know how best to approach it either.
If you're going to take this stance its probably best you don't make comments like your original one in the future. By not wanting to provide any validation you're no better than someone posting completely made up accusations.
