winter claims that I am the one who is offering service which doesn't exist, visible on their trust wall
https://bitcointalk.org/index.php?action=trust;u=100039 and for better visibility:

Well, that is blatant lie and blatant trust abuse, someone please do something because I can't take it any more. My family suffers.
Unfortunately, that doesn't fall into the "extreme abuse (e.g.
Red trust spam)" category; therefore, it stays

Trust spam isn't allowed. If I see anyone posting dozens of fake trust ratings (from one account or many alt accounts), I will delete all of their ratings.

I agree that it is a little annoying to see a wall of negative ratings, but this is in the "untrusted" section. The way things are set up currently, untrusted ratings can be easily spammed in a number of ways. That's why those ratings are hidden by default.
So he actually spams the trust page too because we can see the send feedbacks from
without appropriate references other than the link to his own thread.
