Send an email to Adsense Support and ask for support related to this issue. You will get an answer, probably the best one.
I dont think they would allow me to add more when many publishers would need this option. Example of a MFA > http://www.neattopics.com/
There is a huge list, but the list keep's growing we just can't help so many ppl are making so many MFA's. is there a solution?
If you are a high adsense earner and you write a nice and polite email, Google will probably open an exception for you
