You have a hard time answering a simple question. Tell the members how many PM's you consider "filled up my PM". It will give the members a good idea the way you look at things.
If you thought the discussion was no longer worthwhile, why did you immediately resume it via PM? There were multiple people participating; how is it better to have a bunch of PMs flying around instead of just continuing the discussion in the thread — the thread YOU saw fit to resurrect after 2 months of dormancy?
You got caught being dishonest so now you're trying to change the subject. That's all this is.
