I'm going to preface this with a reiteration of a problem I've pointed out before: Suggest Ideas is not paid attention to by the admins (and if it is it's much less than it should be) and this thread is probably as useless as most threads in Suggest Ideas. But since I care about this topic a great deal and numerous other long-time users miss it I'll be bringing it up (though I would guess it's been mentioned before).
Scripting allowed people to express themselves to a point that has not been allowed on any other mainstream site, period. If a script got out of hand a mod/admin could always message/warn the user or in the case of admins even edit it out. This feature was an attraction, and you could proudly say this is one of, if not, the ONLY mainstream site that allows script/CSS. You cannot say that anymore, and I am dissatisfied with the reason WHY.
The reason why, from my memory of the event, was that people were abusing the scripts. A small issue that contributed was lagging people's computers out (I was part of this issue by having lots of browser ponies dancing around my profile) with how much code you had. The code on my page was too much, but an admin easily edited it out. It would, of course, ask too much to have the few admins scouring our profiles. Instead, you can just have mods send warnings to users doing this, and if it persists, you can just ban the person UNTIL they remove the offending code.
Another issue was people using their accounts to automatically send you to other sites (I heard some of these sites were ads or malware-infectors). This would be an immediate perma-ban in my eyes (though if the user explained it was somehow a mistake you can always revoke such a ban). However you can't ban every account in the world, and as a result of this lack of control when it came to these infecting accounts existing, script and CSS as we know it, were scrapped from KYM.
An easy remedy to this I would recommend, and I am surprised has not been thought of, is simply setting up a system so these quickly-spawned accounts wouldn't ever happen. I would recommend starting things out by making it so a user must show they are not simply being spawned in for the sake of malware-linking trolling. To do this, it must be made inconvenient to create a large number of malware/ad filled accounts. This inconvenience can be achieved by making it so the user must be a part of KYM for at least 6 months and demand they have a standard minimum amount of posts/submissions/edits made by their account. This would make it so you can't immediately go around posting ad-infected accounts, and ensure these accounts had to have a certain level of activity on them.
This insistence that an account must be active and exist for a mildly long time would result in script/CSS acting as a reward for being a dedicated user. A reward like that would greatly boost user dedication and happiness. This increased amount of dedicated users would also increase the activity of the forums since chiefly dedicated users post in them. The forums are your core audience, and a strong core audience affects how well other people are attracted to your site based on the social atmosphere.
Even with all this in place, would it still be possible to create these ad/malware-loaded accounts? Absolutely. BUT, this would reduce them to such a small number, you could easily have mods take care of them in a quick and painless manner and if the account is especially volatile to the point a mod can't access it, you can always ask an admin to help with the situation if it's that bad of an issue. We already have accounts that are spambots that are plentiful in number, so I do not see a reason why a very few ad or malware accounts that are being actively sought for perma-banning by mods would be an issue.
