Most of what happens in so called amusement forums is carelessness and a lack of control over posts and comments, because both men and women participate in these forums. This is undoubtedly a door to fitnah, so people may be impressed or attracted, then try to get in touch via e-mail and the like. Hence we think that this door should be closed, and the amusement forum should be restricted to men, and another forum should be set up for women only for the same purpose, if there is a need for that.
If a man tricks the participants in the forum and enters as if he is a woman (or vice versa), then the sin of that lie is borne by him alone. There is no sin on you, in sha Allaah, so long as you have announced clearly that it is not allowed for women to take part in the men’s forums or for men to take part in the women’s forums.
And Allaah knows best.
