I just noticed that a large amount of ignored users can make Twitch really laggy.
Also just figured out that user block list contains all info about user (like getting info through https://api.twitch.tv/helix/users?login=), was he TOS’ed or not. So, if you want to get info about TOS’ed user, you can just add him to your ignore list and you will get same info. Thanks for replies!
