Let me use your old twitter?

[.]

Looking to use someone's old twitter to spy on a friend. Or a new twitter. As long as you are okay with it. I will only be adding a few people. I will not be tweeting or unfollowing your people or anything like that. I need your username and password
It would take to long to make a new one with followers and enough tweets to make it seem legit.
The person's twitter is set on private/locked so I can not see the tweets without adding them and I can't add them with my twitter.
