yeah sure, why not. I just checked my recent batch upload and yeah I was able to upload 200 videos in 30 minutes several times. There's a chance the OP is referring to one of my channels lol.
Youtoobme has some good reviews in this forum but I
don't use it. I have my own software to play with (YouTube Advertiser). I use YTA because of the multi-threading functionality, which gives you great speed at all times thus giving you time to establish more ways to make more money. I have YTA running on both a VPS and a dedicated server with a 100mbps connection.
There are a couple of things you can profit from with mass uploading.
1. You can steal an entire popular channel's videos and claim them as your own. BE VERY CAREFUL when you do this. I only use this for promoting a local business where I steal popular videos from channels in my country. Do not steal music and movie clips.
There was a time I stole the whole annoying orange videos and upload it to 100 different accounts. Those were good dollar days

I got all those accounts banned after 2 weeks though. I didn't care because the issue then is not that my accounts were banned, but I made such a good amount of moolah that I can replace those 100 accounts and buy 100,000 accounts if I chose to.
2. Mass uploading niche videos over hundreds of accounts. Target different keywords/tags, use multiple titles, uniquify the video so you can upload it many times in the same account, etc.
You can get nice unique videos from fiverr too. Have some pretty face do a script about what you offer.
Start with 100 accounts. If you can create your own accounts, the better. Upload 5-7 videos everyday with each of your account.
So that's 5x100 = 500 videos uploaded daily. 15,000 videos in one month. Now let's say you have a cpa offer or email submit that pays $1 for each submission.
You only need 1 sale or conversion every month for each of your videos. $1 x 15,000 = $15,000 every month.
I know some people here in BHW that I talk to everyday that makes $3k-$7k everyday from youtube alone. Those sons of bitches make more money than I do.
Ofcourse having the right tool is only half the story. You also need to know how to create effective video descriptions and call to action video annotations.
Have fun and Good luck!
