Is it permissible to accept friend requests from women who post non-provocative pictures of women, with the possibility of denying them?

There is no objection to a woman accepting the friendship of another woman in general. However, a Muslim woman should seek the friendship of those from whom she perceives goodness and who will be an aid to her in obedience. A friend influences either negatively or positively, which is why the Prophet (peace be upon him) encouraged the company of the good. A woman posting pictures of women on Facebook and similar platforms that are seen by non-mahram men is a reprehensible act. Nevertheless, there is no harm in befriending someone whom one hopes to influence through enjoining good and forbidding evil, while avoiding those from whom one fears being influenced.
