Sounds cool, I shall run it through the leagues shortly.
Shamelessly using your bot to exploit bits of the system that seem unbalanced is a very good way of getting these issues discussed. It may indeed mean every bot that uses the same tactics beats all the old bots or there may be a way for bots to defend themselves; leaching, chameleon, fixpos all spring to mind as tactics that swept the floor with all the other bots when they were first used.
Anyway, bugs and exploits are a traditional way of winning the league, nothing to worry about on that score!!
I've edited the title of your post slightly so it fits into the bestiary, if non mods can post in the bestiary now I'll move it there, if not I'll leave the post here for a while so it can gather comments.
AFAIK bots are immune to their own species venom and poison, it was made that way because it caused lots of problems for the bots otherwise.
