Do you have a screenshot of them telling you that they are not releasing because you posted it on reddit?
I mean wtf? Thats childish to say the least...
Yes, it was in an e-mail, via the support ticket system of localbitcoins, here it is:

for you already, if that reddit post would not have happened. Now it can
take quite a time to get a peaceful resolution here."
