3rd party service to unfollow without oauth each time??

hey i am looking for a website where i can unfollow users who are not following me like manageflitter BUT i am looking for a site where i dont have to oauth my twitter accout each time i want to use it. something like tweepi where u have an account on that 3rd party website (so i dont have to reveal my ip and can use the site as proxy)
i am not looking for a bot or proxy solution
(a shame the free tweepi cant unfollow anymore)

What's the problem with OAuth?
The authorization takes a few seconds at most with smaller accs. If you have a bigger account, Manageflitter requires some time to load your followers, but it does it in the background. If you have a bigger account and don't like waiting, you can pay for the pro version.

I never had a single issue with Manageflitter and i'm using it periodically on my aged 140k personal account since a long time unfollowing thousands of accounts in one go with the help of iMacros.

I don' think that you'll find a better one than that for free.

You can try these though, but the free versions will be limited:

I use http://www.twando.com/ it still works great, you just need to set it up on your hosting and only use it for unfollowing people who not followed you back. dont use for tweet or dm,, TBH all 3rd party site 's use OAuth.

i want to use the service to unfollow on 10 accounts but then they would be linked if i need to ouath each time i log on on manageflitter
