want to link mailchimp to my twitter account. it says it will be able to:

1. Read Tweets from your timeline.
2. See who you follow, and follow new people.
3. Update your profile.
4. Post Tweets for you.

1. fine
2. as in it will follow people i don't give a fuck about? why?
3. what will they actually do to my profile tho?
4. they will spam my followers with adverts for mailchimp. fine i guess, but how often?
