Let's start with the good. The question itself is perfectly well written in high quality English, is correctly tagged and has a sensible title which matches the body question, all of which are why I personally upvoted it.
So why the downvotes?
I suspect, however, that the problem you're facing is that the question is the main thesis of your question seems critically flawed. You've found two made-up words that sound similar ("Vorta-Vor" and "Vorta") and are asking if they mean that two entirely unconnected things, the Romulans and the Dominion, are somehow related to each other despite there being multiple, repeated references (at least one or more per episode) in the DS9 TV show to the Gamma Quadrant and the Alpha Quadrant being almost totally isolated from each other until very recently.
On that line of thinking, is there any relation between the Vorta and
You might also want to note that we've had other, similar questions in the past and they also faced large numbers of downvotes, also for pretty much the same reason.
What can you do about it?
If you're asking if it's fixable, the answer is 'not really'. It's already well written and the problem isn't that people don't understand what you're asking, it's that they don't like the actual question. That being the case, there's probably nothing that can be done from your side of the screen.
Historically a high quality answer that shows that your question isn't mere supposition would almost certainly result in a big uptick in votes.
