Just hardcoding those saints in a hash who where seen here in the last 2 years would certainly cover 99% of the cases.

I wouldn't fear a DOS attack here, probably cavac should rather be worried about PM's lag and downtimes.

Edit

Such a data structure holding "last here" might lead to another nice feature: 😃

A "Hello <MLX>! Long time no see" greeting 😉

Automated greetings after a long absence!!! I like that. A lot. It's a splendid idea and should be easy to implement!

Any ideas what threshold/timeframe would be appropriate?

I think after parsing saints in our books you can just chart the "last time here" and visually come to one or various natural thresholds.

Edit

If I were you I'd put the whole table into an extra module which is imported by chatterbot and updated once per week.

The threshold for greetings depends on frequency, at some point people might get annoyed by too many of them.

I'd start with 6 or 12 month and would adjust those settings later.
