Building a digg like site in my language

What would be the best way to control spam?

[fourchette]

Hi there,

I'm building a site that's very similar to digg.com functionnality for my language and some niche theme...

I was wondering what would be the best way to control spam?

1) moderate each first couple of posts from each new user to make sure he's serious

2)add a 'this is spam' link to each post so users can flag content as not good

3)require a good amount of votes to get out of modration (too low amount eould be to easy to spam)

4)editor control (admins can delete posts when they see spam)

5) "this is a great link" function avaialble to user with a certain advanced role (good karma)

Any other ideas?

I would like to avoid at maximum spam and totally unrelated stories to be pushed by some organized teens... ;)

Thanks for the help

I think all of those are good ideas, except maybe the "good amount of votes to get out of moderation". I'm not sure how that would work, but if your system is too frustrating for new users that will limit your success. Ideally, legitimate members would see their stuff appear right away.

I have just posted this in another thread here but here is my idea from Digg.

The worst spam are people with pathetic one idea and 50 words blog entries that keep submitting them to Digg.

There should be a limit that prevents posters from sumbitting the same sites ad nauseum, maybe a restiction of 10 times per month for one URL.

Otherwise let the people digg it down.

Thanks for the comments...

I'm not sure how to implement number one :

I tought about sending the first two-three stories to a moderation queue where an admin should approve the post before it even appears on the site... Is that too much?

I 'm sure users would not like to post content that's not even on the site instantly... but again, it would be for only say the first two post...

After they have two posts accepted they can post without going to moderation (directly published on the site).

About the votes to get out of moderation..

My site has categories and each category has a 'upcoming news' and a popular news tab. What I meant is to make it *relatively* hard to come out of the upcoming news page to get on the popular page, so a kid and his friends cannot go to the category front page with 5 votes for example.

Any other ideas?

Thanks
