Ask relevant questions then. Your initial questions were just adding other criteria to be considered "shady" when my assertion was that the simple fact of abusing multiple secret alt accounts is in itself enough to be called out as shady. What I addressed from your initial post was the relevant part, the last one. "What exactly are the consequences / results of their actions?"
Another way to look at it is that ancient aliens from the pyramids possessed him and made him create each account without even realizing it.
You can go ahead and make any number of hypotheticals, but I'll use the concept of Ocam's razor. The very fact that the dev denys the accounts are his even when called out invalidates most legitimate reasons (like separating different projects he is involved in with full disclosure), and we are left with mostly illegitimate reasons. All your another way to look at it are for personal gain at the expense of his supporters. Yes, by making a bunch of secret alt accounts and cross promoting each of them, many subscribers will subscribe to more than one of his accounts without full disclosure. So even if his intent was one of your "another way" the end result is still scummy, and the intent behind the "another ways" you listed were selfish to begin with.
These were not accusations about being scummy. These were evidence, along with extremely likely case of self-cross-promotion with all the "Another Games" sections in his games, for all these games being from the same person. That is, we are looking at these circumstantial evidence, which to me, and probably most people who bother to take a look, show an overwhelming liklihood that all these games are from the same person.
The scummy part comes after that. When taken into the context that each game is under its own patreon. And the fact that they deny this. Which leads to the likely conclusion that he has scummy intentions and is benefiting from his scummy behavior at the expense of his subscribers.
You specifically asked a set of questions. When I ignored them because my assertion has nothing to do with it, you continued to act smugly by pointing out that fact that I haven't answered these questions. I have no intention of answer those specific questions, becaues I never made the claim that this dev was including viruses, or having non-functinoal games, or any of the irrelevant examples of scummy behavior you wanted to tack on as necessity in calling out this dev as "scummy."
