Additional verification required for ACM

What additional information I have to provide?

I can see lots of people have had trouble with this. Assuming you do in fact own the domain, confirm it's not on the Restricted list:

• .RU
• .BY
• Бел - Belarus
• Рф - Russian Federation
• .moscow
• .москва - Moscow
• .SU - Soviet Union
• (http://ru.com/) .RU.COM
• .РУС
• .RU.NET

If that's not the problem then from what I've read, I think you're going to need a support plan subscription for a little while to resolve it.
