Somewhat. If something obviously nefarious shoes up, then they're punished for whatever advantage they're pursuing, not "short logins". Also, saying you have it happen a lot, but have never been pulled aside, that should give you an impression of how ridiculously often someone has to be doing it to get pulled aside, and that's just for an inquiry/warning.

In cases like yours (and I'm just guesstimating, no idea specific characters), it's likely some Immortal may have noticed the login/logout and maybe looked in on it or checked when you did log in, but not finding anything improper, didn't punish you. (Who knew, right?) 😂
