We can't discuss publicly about the ways for reducing comment spam here, but it's still a problem.
The posts have harmful links and several posts are gone after 4-5 hours. It's too long :(

It's true. I wish I could help somehow..

If You can send tips etc. to Philipp privately (not via forum :-) it would be nice.

Maybe more people could get rights to remove this spammy messages. Or usernames....... but just the way it's now makes it a special forum.

I *really* agree to the last point.

At work, I usually check this forum every 3 or 4 hours. And I often delete spam. It sucks.

A good idea should be that if an user(name) has not posted at least 5 messages, he has to fill a CAPTCHA form.

I don't think any of this spam is automated, and a captcha won't stop it.

That's true, and they change username very often.

But let's remember that they are reading this forum and see this thread...

No, that's really not how comment spam works.

The spammers work from low-income countries. They are given a set of keywords, and they search for any web page that contains a target keyword. Then they post their spam. They sometimes read part of the target page so that they can try to make their comment look "on-topic", but they NEVER "read the forum". That would destroy the economics of their work, because they only get paid a pittance for each spam.

Many of the spam posts are vague. That's because some kinds of blog software (e.g. Wordpress) have different spam filtering options for a user's "first post" and their "later posts". You can set up these blogs so that a user's first post is moderated, then if the admin accepts that post the user can freely post again without moderation. So spammers often try to make a vague, general first post that will get past the spam filter, so that they can do their "real spamming" later.

Of course this forum doesn't work the same as a Wordpress blog, but because these guys don't follow this forum they don't generally realise that.

Roger: Very true and due to those facts comment spam really hurts.
I wrote in a common way that it is not a good idea to share here what are the new means how admins will use to prevent spam. Or to delete spam.

How ironic – there is only few posts a day during the Christmas week and most of them are spam comments to this thread...
