1. This is easily disabled in the EggDrop configuration file.
2. It's not the best code in the world, no. But it does it's job, and it
does it's job fairly well. I haven't seen any more widely used bot,
or any bot as flexible yet.
3. This is where a problem lies. We regularly run several bots here for
some small IRC networks we belong to. The only time we've noticed a
problem thus far has been because the *ONLY* remote server has gone
done. Keep in mind, if configured properly, EggDrop has a "list" of
servers it cycles through. If you only have one listed, and that
one goes down completely, it will chew CPU time.
4. While that may be true for some of the larger IRC Networks, I know
many smaller networks that the admins run IRC service bots on (Ie:
ChanServ, NickServ, HelpServ) to protect it's users. People with the
appropriate authority get operator status from the bot, people without
the proper authority get it taken away by the bot, works very well and
it wreaks havoc on the network when these bots aren't present.
