How many retweets until twitter disables them?

I have been using a Retweet bot retweeting by keyword and I noticed my retweets stopped going through and when I tried to manually do one, it said

"Your account may not be allowed to perform this action. Please refresh the page and try again."

Wait and Reply was getting instant banned, but this account is not banned, just seeminly suspended from Retweeting?

Does anyone know at what point this kicks in?

I know im gonna have to use multiple accounts for this but I am wondering how many RTs per hour/day gets your RT suspended so I can make an estimate on how many accounts to use

Ok so I found I went over the actual tweet limit, not just retweet.

The daily limit is 1000, but I did less than that.

Does anyone know the hourly limits?

I am using traffup.net with 9 accounts and they allow only 20 RT per hour up to 3-4 times a day. Are you using bot directly on Twitter or on some site to collect points? Oh, I guess it should some similar to Tattacks bot... and you are RT others tweets. What %% follows you back?

um why retweet for 1000 times per day?
