That has nothing to do with it, Crazy Pete, and besides, my hack doesn't add any tables.

The reason you should empty the tables is because otherwise the bot might just reply with things it's said earlier if that exact question has been asked earlier.

Let say you ask the bot this question:

"Who is Crazy Pete?"

The bot replies with a standard answer like this:

"I remember faces better than names"

Then you go and add this question through vBteachbot, and expect it to return the correct answer. So you ask the bot again:

"Who is Crazy Pete?"

The bot thinks...ohh...someone has asked this earlier, I'll use that line again:

"I remember faces better than names"

However, if you empty the old tables the bot will not remember what's been said to it, and it will return the correct answer (the answer you taught it)
