spam clearing house
Tuesday, October 16. 2007
As you may have noticed, my blogs showed some instabilities yesterday. The reasons for this were some problems of lighttpd in conjunction with php5-cgi. The root cause for this: Trackback spamming(plenty of it) resulting in load problems. Well, this issue starts to get really nasty.
I thought a little bit about this problem yesterday evening, and i have an idea for a Web 2.0 service: A centralized spam clearing house. The basic idea is to redirect all trackback calls to this service, as long their do not come from the clearing house (or trusted systems). The service scans the trackback for spam and submits the trackback on the behalf of the originating server to the trackback functionality of the original server. The same should be possible for the comment function of weblogs. It´s similar to the service Feedburner offers to offload the generation of RSS feeds.
I would even pay some money for such a server, as don´t have to rent faster servers every half year. I even thought about shuting down this weblog in june after the first big black-out of this blog. Fighting spam on different servers as a service would make my life much easier.
PS: Would be a nice job for a UltraSPARC T2 server

Hmm.. danke mod_security hab ich keine Probleme mehr mit Trackback-SPAM. Klappert wunderbar.
Die hab' ich mir selbst gebaut aus Trackback-SPAMs die seinerzeit gesammelt habe (hab' so ca. 1000-2000 pro Tag bekommen)
Aber seit ich dann mod_security zusammen mit Akismet geschaltet habe, erhalte ich max. 1-2 Trackback-SPAMs per Monat

Ich baue mir solche Listen aus dem access.log zusammen. Aber 800 Zeilen config nur zum spamfiltern ist doch ein wenig viel
Warum benutzt die Kombination lighttpd und php5-cgi? PHP als CGI ist ja eine relativ teuere Angelegenheit.
Viele verwenden diese .. vielleicht haette ich noch zusaetzlich anmerken sollen, das ich die erweiterung fcgi verwende. Dadurch bleibt der Webserverprozess leichtgewichtig und der PHP-Anteil besser kontrollierbar.
PHP als CGI erlaubt das ausführen als non-nobody und damit eine bessere Trennung.
Ist eigentlich eine gute Idee, bedarf aber noch der zusätzlichen Verbreitung...
