Yep, that's exactly what i mean, no human does what is shown on your video... we would mostly click on the center of the object cause we can be aware of missclicks or mistakes, a machine can't be aware of this.
I made a similar test myself... Writed a simple cursing script and left it running for around 4 hours, next day ban. Then used macro recorder with no more than a 4 minute recording and loop it for around 4 hours as well, no ban, and i've been doing this with several accounts.
So it's pretty obvious mouse interaction/movement is a big issue in this client.
