You have to filter out the dead and planetlab proxies. About half of the list from Tube Increaser are planetlab proxies. Once you remove them, it is more accurate and faster. It still will say it boosted 10k views, and the next day I still only have like 7k. It used to be accurate, but tons of people are using it now and its proxy lists.
TubeBooster is good, though it could use some improving. When using proxies, if it fails to add the rating, it should try again with a new proxy. With a bad proxy list you could load 100 accounts, and only 75 would go through. So you have to randomize and cleanup the proxylist and run again to pick up the rest of them.
I have heard good things about Tube Spinner and have personally used Tube Booster. I would say either or. Check out the sales page and see what features they offer and compare.
Tube Automator sucks (I still want my refund nova I don't care that I was outside the 30 days. You fail to uphold your half of the bargain by not updating your app!) I am writing a bad review right now! Do you know that I get all of your Google traffic before they visit your site? People that are looking for your app see my site and go there looking for some last minute information before they buy it. I get so many hits from people looking for your software, so I am sure a bad review front and center would be perfect.
