To me the weakness is it's ability to create a new account on the fly.
I was just having a conversation with it it here:

You can see it was able to create HiddenF0x in under 2 minutes.
If we could curve this ability it would greatly reduce the bot's effectiveness. Even something like a 72 - 84 hour ban on posting for new accounts would be effective as most posts start to drop off by then.
Also a manually approval of new users could further hurt the effectiveness.
Last, seems like the bot gave up once I pinned it down. Interesting...
