All I can say, it's really damn good. I didn't get 500k in one day but results for a whole week are very interesting.

My results:

at every 6 minutes i got an average of 390 views
this would be 3900 views per hour
which would be 3900 x 24 = 93600 views per day
this would lead to 93600 x 7 = 655200 views per week

I didn't get 650k but I got 534.000 views in two weeks (I didn't let TT to run 24/7). Counting the hours I let it run lead me to 534k in one week.

I have used one instance of the software not multiple ones.
I guess using multiple instances would lead to a larger amount of views, I don't know, I haven't tried it because I like to take it slow when using such tools.

I didn't managed to get any of my videos deleted so far. Hope it will stay that way.
