Am I sinful if someone I added on Twitter, whom everyone can see I've added, adds me back?

A Muslim woman must fear Allah and not follow people of evil and corruption, for following them exposes one to temptation and encourages corruption, especially if the majority of their accounts involve spreading vice. There is also a concern that adding them might imply approval of evil. We advise you to utilize these platforms for what benefits you in your religious and worldly affairs, such as following the pages of scholars and preachers.
