Good morning,
In mid August I received an “Unexpected exception” email with what I understand to be an attempt to login to the management of an old event with ‘User-Agent’: 'Mozilla/5.0 (compatible) Ai2Bot-Dolma ‘’(+https://www.allenai.org/crawl)'}. This is the whole email:

It sent three more emails in the same minute with the same info. I don’t know if someone just used an AI assistant by mistake, but anyway I didn’t get any info regarding who or from where it might have been, and it seems strange. Any clues?
Thanks in advance,
J
