...in the event that after one on-point reply the content devolves into drivel from the same usual suspects, even attacking the original poster for not knowing....?

Just wanted to apologize for deraiiling your thread.
Was not my intention.

GaG, CDL, etcetera, just hijack thread after thread and go off the rails.

I think you request the admin to delete the post.  They will often do it, though it could take hours/days for them to get around to it.  
.
I believe it is under "Report this post" then fill out your reasons.

People get pissed at things all the time and the boards are a good place to vent. As long as your rant is "on topic" and it most certainly was,  there is NOTHING at all wrong with venting a bit.

and here is the reason.  Regardless of the twists and turns a thread takes, other members have taken their time to respond or join the conversation. When you take down a whole thread, you made their time and contribution worthless for EVERYONE, not just the responses you didn't like. Its very disrespectful to other TER members, and makes you look like the board Nazi.   I have both started and joined some train wrecks myself, but I will just walk away and let the others have their fun with the topic once I get a few responses that are worthwhile.  If not, you can join in at any point and try to steer it back to get more of the kinds of responses you want, but shit-canning the whole thread does not encourage people to participate in future threads of yours. What is the point if there is a likelihood from your past history that the thread will disappear.  There was a guy on the Kgirl board that used to do that, and he soon found when he put of up question, no one would answer because of his propensity for taking it down the next day. Trust me that you don't want a reputation as a post-puller.  Of all the sites that are considered some form of "social media", TER is one of the last bastions of truly free speech without censorship.  Just follow the posting guidelines.  We should all embrace it.  

I’ll answer your question and tell you how to do it. However, first I actually agree with most of the other posters. I say just leave it, and let it run it’s course. I don’t believe in deleting a post just because the thread took a turn you didn’t like. I also looked at your thread on the Kgirl board that I assume you were talking about and it doesn’t look bad at all.

Ans it's usually by the same cast of characters. Look, a little side bar is ok but when the main topic then isn't the main topic that's when the thread just becomes a pissing contest.  
Some guys just need to get their ego in check and I wish the Moderators of this board would clapped down, at least just alittle.....But good luck on that

and the ability to edit your post is still listed under the Action menu, just delete all the text, and put "deleted" in the subject line.

This is called hijacking a thread. The thread could be a quick  informative read but instead it becomes a trash heap  of name calling and general buffoonery.. Don't attach it to my content please.  I'm trying to create useful info, not another place  for you and GaG  and papa to cock-whip each other.

I can't find any of his/her posts. Want to know just how creepy he/she is.

These are truly discussion boards -- not a really a threaded topic board. The entire architecture of the software seems distinctly different from any of the bulletin board type s/w one sees in most other online forums.  I think it mostly best to think of being at a party -- your comment may well just spark a discussion that goes quite far from the original topic.

I have some of those 'internet gangstas' on my ignore list, so I can't see their comments anymore. Just select 'ignore user' from the drop down.

...naming me as one of the "hijackers?"

I'm sure I've got something relevant to add.

of how TER works may be confusing for you because of prior sites that you posted on.  There is no "ownership" interest attendant to starting a thread.  Once you post your OP, it becomes TER's property, not yours.  Same with reviews.  With reviews there is consideration in the form of VIP days, so you are actually "trading" reviews for VIP days.  I've noticed several times that you BA guys that all came from the other site often refer to threads you start as MY thread.  That really doesn't apply here in the same way it did over there.  OP means "original post(er)".  That's it.  After that, your rights are the same as anyone else that posts on the same thread, including the right to take it down, but that is seldom done and not a good practice, as others have also pointed out.  

First, do you feel any better with the answers provided?

Thanks for asking.  I would  just appreciate staying on topic. Wanna throw shade on someone? Start your own thread.

my point about there being "no ownership interest" in a thread when you continue by telling someone to "start YOUR own thread."  (emphasis added).  This is not that other site you used to post on.
