Both of you are in the wrong here. Tagging someone as a suspected alt is not right as people have already stated, but retaliating with feedback isn't correct either. As far as I see it both need a ~ for now until you can show people to trust your feedbacks.
AHOYBRAUSE what you did does seem pretty suspect. Noone asked you to do them a favor did they? You created this mess by sending the message, and you continue to feed the fire by leaving the retaliatory feedback.
See what I mean, what is CryptoHFs even talking about, enemy what? I don't even know you.
I left the feedback because he didn’t reply when I kindly asked him to clear this up. He just ignored me. I thought this would bring him to his senses and finally reply. Also I want this thread to be linked in my feedback so that people can see what his bs tag is about, there was no other way. If he does this abuse to me he will do it to others.
From now on I will stay away from doing possible favors. I only did this because I saw his thread and later the other post and I remembered the first once. Never saw this kind of deal before and thought it was a perfect fit. I thought in a community people can help each other out, guess I am wrong.
Anyway, my feedback with the link to this thread stays until he comes to his senses, what I unfortunately don't see since he acts like a strange person.
Edit: He removed it and so will I , will lock this thread for now and will also be more "careful" with what I think is a kind gesture. Thanks for all the input.
