Actually, I did a search, just for the hell of it. My memory is fine. There are 89 posts of mine where I uttered the phrase "Coldplay" over the last decade or so. The vast majority of them do not fall into the category of what you originally stated, that of "rip(ping) Coldplay".
At least half of them were in the context of an argument about Eric Clapton comparing U2 and Coldplay (woohoo that was a fun one, I was actually ripping on EC's utterly moronic statements on U2). The next 25-30% of them are me making sarcastic jokes about people who compare Coldplay to U2, and then a few more of them just vague references to earlier in-jokes.
More recently, I conceded that I don't really hate their music per se, but that I find Martin to be an insufferable twat.
Even more recently, I actually stopped just short of complimenting them on parlaying an Eno-esque riff into something massively successful, while U2 did not.
I didn't say I hardly ever talked about them. I participated in discussions where they were already being talked about. On rare occasion, I did state my opinion specifically on their music. But certainly I don't have a track record of bagging on Coldplay. That must be someone else.
