What should I do with each individual girl whom I have added as a friend on my Facebook page? Should I keep them, delete them all, or delete only those who do not respond to advice? Note that I do not initiate conversation with some of them, while with others I respond to their questions about studies or religion, or I admonish them for mistakes if they publish a fabricated hadith or erroneous religious discourse. With yet others, I do not admonish them for the reprehensible things they publish, as admonishment is useless with them. Is the game Pool Live Tour permissible, given that it relies on betting with money granted by the game administration?

The basic principle is that there is no harm in a man adding a woman on Facebook or other social media, if there is a legitimate purpose and the Islamic guidelines for interacting with women are observed. This means that communication with them should be about permissible matters, for a need, and to the extent of that need.

As for whom you can keep added and whom you should unfollow, that depends on your knowledge of each one of them: whether she is keen on benefiting or not, and whether you expect her to observe the Islamic guidelines in her interaction with you or not.

However, if you are at the beginning of your journey of righteousness, and you do not possess much knowledge to repel doubts that may arise, nor strong faith to ward off desires and temptations, and you fear temptation for yourself, then it is better to avoid adding any women and to be cautious in dealing with them at university.
