DISQUS

D'une part, je me permets de suggérer l'écriture de deux articles distincts, un par langue, afin d'améliorer le référencement et de cibler ses lecteurs. Ensuite, je recommanderai l'activation du plug-in Akismet, car visiblement, le seul commentaire de l'article est du spam. Ca fait mauvais genre, de laisser un commentaire de spam durant une semaine... On dirait un blog à l'abandon... :-S

I'm afraid there are few companies that check their data for inconsistencies. Have you read the Google report on third parties click audit reports?

How Fictitious Clicks Occur in Third-Party Click Fraud Audit Reports
http://www.google.com/adwords/ReportonThird-Par...

where you can read:

"Events identified as fraudulent in these reports, which actually match real clicks in our logs, often converted at nearly the same rate (and in some cases better) compared to other clicks. For example, in one case where 800 paid clicks were marked as "fraudulent", the rate of conversion for these clicks was 5.1%, which compared favorably with the 5.8% overall conversion rate the advertiser achieved on approximately 24000 paid clicks."

Can you imagine a click fraud spammer BUYING anything on a promoted web site? It appears nobody cares...

Elliott, I've been deeper than you did: I blocked blacklisted IPs (using miscellaneous DNS RBLs) from viewing my blog, so even referrer spammers have been blocked. The main issue was about 5 to 10% real visitors were blocked as well.

For sure, using DNS RBLs filters more spammers. However, it also filters legitimate comments as well. The main issue here is people who post comments often have blogs. And they talk about other blogs. If you reject their comments, they won't comment your blog, they won't come back to read other comments and they won't talk about your blog neither.

It's probably better to have to remove spam manually than preventing opinion leaders (what other bloggers are) to participate to your blog by leaving an interesting comment on it.
