I am almost 100% positive that this account is compromised. Unless proven otherwise, I will not be removing my rating (regardless of the validity of this accusation). Do not PM me again unless you have conclusive proof of being the same user as the one in 2014.
This is a complete joke.
I will be opening a thread shortly. How can you be almost 100% positive, with absolutely zero evidence?

Lauda, corrupting the user-base like a poison, user by user.
There's quite enough evidence against you to arouse suspicion. The fact that you haven't posted since 2015 and then come back trying to do trades straight away and can't prove the account is yours is good enough for the feedback as a warning. If you can prove otherwise then people will remove the feedback but it really doesn't look good for you.
You have an address posted here:
Hope this helps! If this works for you, I would gladly accept a belated Christmas present from you.
