Is my method of inviting non-Muslims on Twitter correct, and what should I do about followers who post obscene pictures or polytheistic speech?

The best and safest ways to invite people to Islam are by referring them to reliable books, audio, and video materials. The book "My Love for Jesus Led Me to Islam" is trustworthy, and it is recommended to continue publishing authenticated tweets, books, and videos to invite Christians and others [to Islam]. Regarding deviant followers, it is preferable not to block them unless they put pornographic images in their profile pictures; in that case, it is advisable to block them or delete their comments.
