"He also calls Neko a liar." You can't quote the post, so that is either a mistake or a lie.

"Marty won't respond to Neko...". With the numerous responses to Neko, that appears to be either a mistake or a lie.

".... blames Neko for his refusal." Since that was never said, that is also either a mistake or a lie.

It would be reasonable to expect quotations supporting the allegations, or a deletion of the post.
