Will Accounts Get Banned If There's No Visible Activity?

Here's what I'm wondering...

Lets say I made 250 Youtube accounts from a catch all domain, now the only purpose that these accounts will be used for is rating, favorites, and subscriptions. The subscriptions on my channel will be hidden, so no one can actually see what subscribers I have, just a number count.

I would not use these accounts to message or comment on any video. so basically these accounts would be invisible to every user on youtube.

If I'm not able to get one account banned is there any reason that youtube could find to even look at all these accounts from a catch all domain?

I know people have been getting accounts banned when using these emails to register, but I'm wondering if it's because they brought attention to themselves with comments or with friend requests, or even as far as posting videos on these accounts.

I made 250 accounts about a week ago and all of them are still alive and working, so maybe this will work as long as you stay invisible.

What do you guys think?

1. I believe favorites are shown on the video within the 5 minutes the account favorites that video.

2. The last 5 people to rate a video are shown under statistics.

3. You are more likely to get your accounts banned because YT saw 250 accs made under the same ip/domain.

Hey,

You are better of creating the accounts using gmail or some other account provider!

I have not run into that problem as of yet
