what is tweetadder ? is that software or website ?
I'm taking it real slow. 10 a day. 30 follows a day and 10 unfollow a day! that's it for now! the same for all my accounts.
Only tweeting 10 a day! all same tweets but randomized!
That should be under Twitter's spam limit. I believe that you do not need any proxies with just 5 accounts and the low follow/unfollow rate . But remember, Twitter is a number game. The higher accounts you have, the more people you can reach. Also, make sure you are following people in your target niche. A good ratio is 1 proxy for every 10 accounts.
Good luck!
