How Many Links in only one adsense unit

I am very curious, how many links does appear max in any adsense unit? On my pages I have maximum 5 but I see sometime some other pages, that they have more than 10 links in only one unit.

Does anyone know what actually they do? Is it ok or maybe they changed the code in Google Adsense script?

I will be happy to see what you think about it.

 

I think they change the code

 

Do you think, is that against TOS?

 

one unit cannot have 10 links. if you see 10 links on one ad unit, then it must be someone put 2 adsense units side by side showing total of 10 links which is very common

 

If you combine two ads then you can see two times it is saying -Ads by Google- But what I found in internet, it is not saying that.

 

Can you show as a example of any page where such ads are being displayed?

 

I think they put 2-3 adsense units site by side,
1 adsense unit can't has 10 links in it.
