There doesn't appear to be any character or size limit on what can be saved in the personal notepad. Therefore, it could be very well possible for someone to type/paste as much text as they want in there, save and maybe fill up the database?

Perhaps an ACP option to limit the amount of characters or size it can take up in kilobytes.

FWIW, how many MB did you paste in there?

I didn't calculate, I doubt it hit a high amount of megabytes, but a good amount of kilobytes for sure, might not even be possible to do it this way but someone could very well write an automated script to do so.

64k is the most the DB will ever save for a TEXT field regardless of input.

This is not a bug in IPB but is more of a feature suggestion.
