Created attachment 99786 [details] Moderation requests in September 2009 Since mid November 2009 the average load of moderation requests dramatically increased due to migration from CollabNet to Kenai infrastructure. I analyzed data from September 2009, January 2010 and May 2010 and found out that this increase is obviously caused by worse spam filtering. Please look at the attached charts that prove my hypothesis. While before the migration it was necessary to reject only ~14.1 spam messages daily, it is now 4 times more! Month Average # spam Maximum # spam Average # valid e-mails =============================================================================== September 2009 ~14.1 26 ~32.6 January 2010 ~48.5 105 ~31.9 May 2010 ~60.6 182 (!) ~36.4 Due to this unfortunate trend we had to hire two more volunteers as mailing list moderators! So, can you please get rid of current spam solution and use something else for example SpamAssassin [1]? [1] http://spamassassin.apache.org Thanks a lot! Jiri Kovalsky

You might be surprised to learn that we use SpamAssassin from day one.
OK, I updated the SpamAssassin throw-out limit from 6.9 to now 6.2, let's see if that makes difference. I have to be careful because we don't have anybody who wants to fish false-positives out of the 1000+ messages/hour we throw out already. And that's after the 3000+ messages/hour which we reject right away. I'm also working on updating some SpamAssassin helpers but that needs extra help from the network people. And I don't know when that will happen. So, please update this bug with the stats for the next week and we can look after that. Thanks, -- Marco
I will do Marco! BTW, isn't it possible to teach SpamAssassin on the spam messages that went through? We have thousands of these in our moderator's e-mail account. Let me know if you are interested in this. And thanks for enlightening me - I am surprised indeed. :-)
Created attachment 99981 [details] Moderation requests in the first decade of June 2010 Month Average # spam Maximum # spam Average # valid e-mails =============================================================================== 6/1 - 6/10 ~59.4 84 ~48.4 My interpretation is that number of spam is same :-( but maximum is lower :-) while more valid e-mails goes through! :-) I think it's still early for deeper evaluation. Let's wait for end of June. Does anybody else have other opinion?
Jiri, is this issue still valid ?
I don't know. I turned to our mailing lists moderators [1] and will update this issue once I know more. [1] http://netbeans.org/projects/www/lists/moderators/archive/2011-11/message/0
I have moderated for over a year and things were poor to start, but then got a fair amount better. I think I probably deal with 50% less spam now than at the worst periods. I think "vacation" spam was dealt with better this summer versus last summer for example. It is difficult to quantify, but moderating has been easier the last several months.
(In reply to comment #7) > Jiri, is this issue still valid ? I started receiving tons (~50 a day) of spam a week ago through various netbeans.org mailing lists (commits, issues and other lists). A misconfiguration of spam filters after the site upgrade?
I also experience way more spam these days than it used to be a week or two ago. Honzo, can you please file appropriate issue in Kenai's JIRA system? It really looks like a misconfiguration after the recent netbeans.org upgrade. Thanks!
I started kenai ticket for this http://kenai.com/jira/browse/KENAI-3121 honza
Fixed by Marco from the kenai team. His message: Should be back to `normal'.
During the last weeks I'm receiving a lot of spam over my @netbeans.org address. Most of them use Content-Type: text/plain; charset="koi8-r" Could you please prevent this? In fact I'm convinced that it's not necessary that @netbeans.org addresses should be reachable from the "outside". I mean it's surely enough if the bug tracking system and the mailing lists can use it.

Current stats show that percentage of SPAMs crossed 85% of emails from moderated mailing lists, moderators needs to filter-out incredible percentage of emails : ( Spam, Moderation requests, Month) 30% 1401 September2009 72% 4463 August2010 87% 3779 March2013 I do not think it's acceptable in any kind of community, to cover job of SPAM filters by human bodies !
