I don't know how to interpret ALL of the info but, for starters, NONE of the "official" sites list lilythaiclub as being her site.

No websites listed. (Many other pornhub bios provide the actresses websites.)

Official Website: zilch
Says she was active from 2003-2005 only. I.e., shooting new scenes from 2003-2005. They will be re-re-re-releasing old scenes in NEW compilations forever, so don't go by the freshness date on a new DVD as evidence that she is still shooting NEW scenes.

Lists her twitter and FB only. Those are probably managed by others (studios she worked for? manager / agent?) so don't expect to be be talking to / messaging Lily.
The newest release with her is from 2021. Assume that it is old scenes in a new package and NOT a new scene she shot in 2021 when she was 40 yo.

Hold on to those old VHS tapes and DVDs. And hold on to those memories of Lily Thai when she was 22 yo and shooting hot scenes.

there was a guy on Reddit that claimed to be dating her, and said she might re-enter the business.  He did provide some form of proof as I recall.
