That's a case where a cease and desist is fine.
Impersonation is well beyond that type of thing.
This is a very serious crime if a person is creating the ads. Also, selling a console with roms is a unique case too. I also don't know the details behind it either. But that can also be a quick cease and desist because it's a literal single console and was already sold. Best they can do is quickly take ahold of the item and maybe sue the person if they need to. They're still taking action however via requisition. They actually did try go after Youtubers before, actually. They changed their policy later on to avoid losing their IP's by allowing people to use it for revenue, fixing the issue. The important part is they have to take action in some way, which can include changing policies to get around losing their IP's. Impersonating is not something remotely like a single one of those cases. This is way more like the romsites which was used to make tons of money. Which they did take down because they lost millions of dollars in potential sales(if the person was distributing free roms, or a single console one time with roms, it's not nearly as serious as a crime. Especially since one can literally just save all their game data on a memory card, which is very similar to the console rom situation, sell it, and there's little to be done about it. There's actually a lot of official old game console variations that are sold worldwide. It's not as easy to go against, but they're also legal enough they can't take action. Soulja Boy is in a muddy enough area where Nintendo won't lose their IP's either. It was a lucky break for them, so they aren't forced to go against it).
You're still comparing apples to oranges, however. Once again, the only comparable situation thusfar that they've gone after is the romsite, which actually sold roms(instead of letting people download them for free, which in the case of "free", Nintendo isn't forced to go after them, but still can legally tell them to cease and desist). It's a hefty money situation, and constantly has tons of ads that affect potentially billions of people. It's far more serious than people seem to realize. This is a huge deal if it's fake. This is ignoring the factor that a lot of companies have their own IP's being messed with too. It's a big deal for them as well. Besides that, these are ads for the Fighter's Pass, which directly is affecting Nintendo money-wise. Of course, that's if this is fake. If it's not fake, sweet. If it's fake, that person pretty much is going to be so far in debt they'll be bankrupt.
