I think this would be the problem:

the eggdrop identifies a person by nickname... and granting rights to the person with the right nicknames.
if it's on a network without registration services, the person could 'steal' the nickname of the bot owner easely and gain operator status that way because he can then order the bot to op him/her/it

you should get a more secure bot I think...

If it ain't broken, don't fix it!
