As-salaamu `alaykum.
If anyone is being pestered, do notify mods, we have banned people before do to their persistent proposing, talking to sisters in private WAY too much etc. This site is not a matrimonial service, and if there are people who wish to propose, then please do it in a more professional, shar`i manner, not via a private message. A new saying goes 'woe to internet courting'.
As a word of caution, we should be careful when we post, as many, many people will see what you are going to type, try not to come across in a way that could lead to proposals (I'm not saying anyone in specific is). Sisters especially, please try not to show too much emotion in your posts, start by cutting back on the smilies and lols! Many sisters here maa shaa' Allaah, they type highly beneficial posts, are active on this site, and they come across in a way in which I personally believe no one will bother them, at all... well, maybe the odd person or so.
The `Ullemaa' have spoken even about forum etiquette, so let's try to observe them inshaa' Allaah, especially when we talk to kuffaar and the opposite gender... care needs to be taken.
Allaah knows best.
