This started with
making an 1k ISO topic. When i showed up with the item he started making up excuses to avoid the deal. (Which is childish, but not against the rules)
Here is the topic:
https://forums.d2jsp.org/topic.php?t=96495399&f=123&o=0Then he decided to buy another item that did not meet hi ISO requirements for cheaper and gave me 100fg for my trouble of spending my items and time rolling for his item.
I decided to give him my opinion on that matter, which is "If you wanna back down a deal because you regret offering too much, just say it and renegotiate the deal. That's not an issue, just solve the probelms as a mature persn"
He kept the excuses in topic. As the same thing happened to me the day after that, i decided to make a signature to warn ppl about players that do not fullfill their topics and make up excuses, which is not aganst the rules.
Here is the dialogue through pms and my new sginature:

Well, after this i thought everything was over, but today i was giving a price check opinion in a topic and someone marked
, because he saw my signature.
Then he came and made an offensive post marking me. I reported it and then he eddited it and started sending me offensive pms:


I answered the first one politely asking him to just learn with his mistakes and stop making excuses for issues that show up for him, also to grow up and stop behaving as a chidl.
After he sent me the second and worst pm, he blocked me.
Well, imo this behavior was very toxic and i'd like to know if he's gonna be punished or warned, something like that...
I don't think this kind of "trash talk" is allowed, even through pms...
Thanks for the attention, hf and ss
