I'll explain why there is such a rule with regard to being in a party with bot.
In your opinion, how should bot-hunters find out if it is your bot-character on box (dual acc), or you really play with your hands, but in a party with someone who uses a bot, and you did not know about it? I assure you that every second player in the ticket claims that he "does not know" that he is in a party with a bot, even if it was his 2nd box. (Although as for me, if you are an experienced player, there is a very small chance that you may not notice the automation of the process, since it is more often visible to the naked eye).
Or another option: you play with your hands (do not use bot), but you KNOW that you are in a party with a bot-char (even if this is not your dual box, but ramdom player).
Now, do you understand what I mean? It is impossible to determine whether you are in fact a random "victim", or deliberately violating the rules.
98% of players do this consciously - that's why there is such a rule about being in a party with a bot.
