I'm using eggdrop 1.6.17 on a FreeBSD 4.10-STABLE box. I use all the bultin protections. Once I tried to shitlist a guy, the bot didn't ban him, just kick him with the reason "requested".

It didn't ban him and it doesn't either ban shitlisted people.
most likely your channel ban list is full, or has reached the max-bans value that you have set in bot's config; eggdrop won't enforce bans over that limit
