Quoting a reply from brother @
Muhammad regarding the old 'Marriage in Islam' section,
The 'Marriage in Islam' section wasn't meant as a matrimonial section - we have always discouraged using the forum for that kind of purpose or even promoting other matrimonial sites here. Perhaps the intention behind that section is better reflected in the current Family and Society section.
If I remember correctly, the section was closed down in 2007 due to numerous problems. Later, a new section (Family & Society) was made which would cover a broader range of topics, not just marriage. The key was that it was meant to be better moderated and not a return to the old marriage section, rather something of actual value and benefit. The word 'marriage' was deliberately kept out of its name. Another important thing to note is that the new section was among the list of sections within the 'Learn about Islam' category, whilst the original section was not linked in this way, which again signals the direction of hope.
So, what were the problems with the old marriage section which we were so keen to prevent happening again? People were posting ridiculous threads there without thinking, such as what would you do if your wife slapped you, or would you marry someone who... this was really getting out of hand. There was idle chit-chat, free-mixing and too many unnecessary hypothetical questions. It didn't seem to actually serve a purpose other than being a place for kids to fantasise about getting married. It was simply being misused and too often.
It had also become very difficult to moderate. It was difficult to separate nonsense and fantasy from legitimate concerns. And there was the long-standing concern that we are not marriage counsellors therefore people should not be encouraged to post their problems here.
Unsurprisingly, many people including members and moderators were in favour of that section going. The new section was only brought about with caution and careful observation to ensure we would not end up with the same issues.
