1. Firefox
2. Im using extensions for Twitter for months now. Changes half of my UI.
I doubt they care about an extension that looks at posts and copies them.

Skybridge Extension did something similar and looked at Twitter Follows and searched for similar names on here.

Nah, there are 100% ways to do this without Twitter API.
Like an extension that automatically tracks when you tweet something and creates a draft or post for the other site/s.

Would work only in browsers with extensions tho. :I
