That's only a few references over like 2 or 3 years, and some of them aren't even direct.
I'd say he probably doesn't have any more of a grudge against her than any more well known forumer.
No, but his adamant statement that he doesn't particularly know Bubbagum, nor has had any form of interaction (let alone been rude) is blatantly incorrect.
It also doesn't take into consideration any times he didn't say "Bubbagum" in his message. And most of those examples come from times he has quoted Bubbagum. There aren't any of where he may have been rude towards/about her without using her name or quoting her.
And yeah, the majority of those were from 2 years ago, but people do remember things. And indirect or not, if the same person has been there on several occasions having a go at you or being rude, it'll stick in your mind.
They might not believe they have a problem with you themselves, but that doesn't mean it can't look like it.
