Yup I have all of those accounts, as well as 15 riot accounts lol…
The only 1 that blocks SL (at least the “slmail.me” domain I use as my default) is Epic Games, I had to use my custom domain for them. Every other one mentioned I use an alias with no issues.
Edit: If you do have a large amount of accounts like I do with Riot I would advise not swapping them all to aliases at the same time because its technically against SL ToS to use aliases to have multiple accounts, although in reality they just a rate limit.
So if you make a few aliases for the same service, space it out over a week, or you’ll get auto locked, and it’s a pain in the butt to unlock through support.
I’m 90% sure it’s detected by incoming confirmation emails’ domain. (Ex: it will detect if you get 4 Riot Games account verification emails to 4 different aliases within x period of time)
