So basically FIDE Online Arena elo is nothing different from chess.com elo. In the sense that it means absolutely nothing outside of the site?
The FOA titles are official, they are displayed on the player’s FIDE profile as well as at official OTB events. Unlike over-the-board titles, the FOA titles do not differentiate by sex and apply to both women and men equally. The online titles are automatic: once the player reaches a certain rating and is able to maintain it for a required number of games, they are eligible for the online title. You can obtain the FOA Title recognized by FIDE by playing FOA-rated games on FIDE Online Arena. What are the exact FOA Titles: 👑 Arena Grandmaster (AGM) — Rating 2000; the player must maintain the rating at or above 2000 for 50 games for Rapid time control or 100 games for Blitz or 150 games for Bullet to qualify for the online title. 👑 Arena International Master (AIM) — Rating 1700; the player must maintain the rating at or above 1700 for 50 games for Rapid time control or 100 games for Blitz or 150 games for Bullet to qualify for the online title. 👑 Arena FIDE Master (AFM) — Rating 1400; the player must maintain the rating at or above 1400 for 50 games for Rapid time control or 100 games for Blitz or 150 games for Bullet to qualify for the online title. 👑 Arena Candidate Master (ACM) — Rating 1100; the player must maintain the rating at or above 1100 for 50 games for Rapid time control or 100 games for Blitz or 150 games for Bullet to qualify for the online title.
Thats on the FOA website, not sure if this helps, I'm looking into as well.

She looks like a real person to me. She is a FIDE Arena employee. I think she is the one who emails people (if I am not mistaken). Where are the other "I've counted 48 bots so far". I am also new in FIDE arena. I just paid premium membership. My experience is very good so far. I read chess books. I am practicing here in chess.com. I play rated serious games there. And it is improving my game. Overall, it is getting me motivated to train hard. Trying to get AFM through rapid. And maybe will train blitz for arena IM if I cannot get it in rapid.
I don't deny that there might be a real person by that name (there's certainly a real person in the avatar picture) and that real person might be one of their employees. But a real person clearly isn't playing this account's games. Real people don't average a quarter of a second per move every move of every game. And they don't forget to recapture on the same queen exchange a dozen times. If you go to the Cheating Forum on this site, probably 100% of the people you ask will tell you that's a computer playing.
Now, to be clear, none of the games I played were FOA rated. You need a paying account to play those, and I don't have one. These were all played using the site's regular rating system. If you only play FOA rated games, that might explain why you haven't seen it.
Oh ok, maybe your points are correct. I have not experienced robot suspicion in the premium pool yet. All games I played so far feel so human.
