In the first video you are getting interrupted approximately at 30-40% of the total cast time and in fourth video you are casting more than half of the ability and then you get getting interrupted, which means that it's not possible the player to use kick bot because kickbot literally interrupts spells at 0.1 second. In video number two, you are casting in front of the DK and it doesn't seem like an auto kick since it's not an instant kick. Also, at those videos I mentioned the DK is using his abilities and auto attack that's why the cast goes backwards, this shouldn't happen with a kickbot.
Regarding video number three, it's the only proof I see that the player might using third party software but I won't ban someone for this since I observed his whole game play at your videos and there are no indications of violations.
Declined.
