After reading my post MRO Aviation got in touch again. The red and underlining have been added to draw attention to what I consider the most egregious sections of the messages received.
MRO Aviation: Good morning
MRO Aviation: I'm seeing from your online posts that you enjoy conflict and trouble. I just saw a post and I have proof that we simply haven't hired you, not because we can't, but because my school is extremely full and I'm not interested in the kind of work you bring in. I'm politely requesting that you remove your damaging and unfair posts about us today, otherwise I will take legal action.
I will write to the CAA and our friends so that you'll have problems with them when you apply for your license, among many other things.
MRO Aviation: As you can imagine,
I have very powerful connections everywhere and could ruin your future, especially by spreading lies and nonsense about my company. So please remove this post or we will be forced to take further action...
Me: Happy to delete any part of what I wrote that is factually incorrect. Please feel free to quote any falsehoods contained. However, if i continue to receive threats from you I will publish them alongside the original post.
MRO Aviation: You can do whatever you want
MRO Aviation: You will be in my focus
