The best tip I received in that thread was from Nitrous, suggesting to aggressively ban unrelated ads appearing on my ad blocks.
Starting from this suggestion I achieved further investigation and found that in fact my ads are plagued by *around 50%* of unrelated ads, mixed with perfectly in-topic ads.
Give the fact I use section targeting for every new content since many many months, the strange part is that:
1) Google stopped presenting a single or two advertisers on a large rectangle (as we saw since end of 2005) *just on the first block* of the 3-repetition.
2) unrelated ads appears in a mixed fashion along with in-topic ads *in the same ad block*
3) this happens *only on the first ad block* of the 3-repetition on my home page (where I get more clicks than everywhere else).
The 2nd and 3rd ad blocks are quite never plagued by out-topic ads: they still present just 1 or 2 advertisers and are always on-topic.
4) On the previous thread someone speculated advertisers runs out of daily budget. This is not the case since the same on-topic advertiser *always* appears on the 2nd or 3rd ad block.
Let's do a practical example:
in my home page there is a large block ad repeated 3 times.
On the first ad block 4 advertisers appears: in a mixed fashion 3 of them are off-topic and 1 is on-topic.
On the 2nd and 3rd ad block just 1 advertiser appear and is always on topic.
This happens more or less identical every single day since I started to note lower incoming and to track what was happening.
Aggressively banning these off-topic ads raise my eCPM back to decent values but it stays there for few hours.
I need to check ads and ban off-topic advertisers all day long and is quite complex.
I also tried to adopt another ad block format, smaller, to provide less space for off-topic advertisers but it performs worst than large rectangle so I went back.
So, at the end of the day, my idea of what's happening slightly changed.
This could be a bug or an expected behaviour but there is an evident pattern reading carefull my notes.
It seems an injection...

That is really leaving us in suspence, Giano!
Please explain us more..
It's just an idea.
Re your injection idea--that's not exactly how I'd put it, but Google does roll out new ads periodically. If they perform, you'll keep seeing them. If they don't, they'll disappear. Which is another reason not to block them--in most cases, provided they aren't site-targeted, they'll disappear anyway.
