Salafi marriage bandits was from 2002 - 2013 it's over now.
One extremely common tactic used both by the cyber-predators as well as the local ones is religious and emotional manipulation: pressuring these women to marry quickly to “fulfill the sunnah” and “protect their desires.” For women seeking stability and a life partner, the combination of emotional blackmail (a woman who does not get married quickly is not a good Muslimah) and flattering attention (“You are such a pious, wonderful Muslimah and I must marry you in order to protect myself!”) can be very persuasive.
