clickadu.com - who are they?
 

clickadu.com ad network, any info on them? Are they russian?

I think both adsterra and clickadu are Russian owned but without official confirmation cannot be sure.

They spammed me with their offer and the contact person name was Sergei (i think a russian name)

Fuck russians. Never going to touch it.

Aren't they from Hungary?

I think they are based in Russia.

I'm not sure where their headquarters is located, but as far we know it is a reliable partner. We have been doing business for a long time.
