is it possible to ask google to check your site .. and ask them if all the ads block and blend if fine... so that you are safe from any risk of losing the adsense??
Do you think that the adsense people have no other job than checking your site for blending of ads...like that? They rarely care to check if you ask. If they find any violation of TOS, most of the time they will warn and rarely ban without warning (in serous cases)
you can ask them but they wont do it. they will refer you to the TOS page. its your responsibility to abide by the TOS
Well, I did tried to request Google to check my site, and see whether it complies with their TOS. It's possible.
I think it would depend, i would say in most cases they would do the checking if they have received a compaint but i cant imagine they would have enough time to do it upon request too often for too many.
