Non Registered Users With Usernames

[Catullus]

Who are these people who are not registered, and have names on the Tetration Forum? Like once on May twelfth two thousand, twenty-two it said "53 users active in the past 15 minutes (1 member, 0 of whom are invisible, and 50 guests).
Applebot, Baidu, MphLee". But Applebot and Baidu do not have accounts on the Tetration Forum. Why are there users like those users that do not have accounts, and yet still have usernames?

Just search engines , bots and IP numbers of people surfing to this forum.
