Best way, in dealing with Tweetie ... is to not respond. Just leave each of Tweetie's posts simply hang.
Personally, I find some of Tweetie's posts amusing .... sometimes to the point of being downright funny.
We've seen trolls since the inception of forums. The old ricky ratford trolls (and that sort) weren't the least bit humorous. Often, down right disgusting.
However, if you read a Tweetie post, snortle a tad and just not respond .... Sometimes, it's best to simply let a sleeping dog lie (pun intended or not intended).
