Monetization forum. Part two

Exactly one year later, I wrote a question about the monetization of the Moscow Region Forum. Thanks for the advice and recommendations.
He took into account what he left for later.
The Year has passed, the strategy is the same: hold out as much as possible and fill up the forum with non-thematic advertising.
Attendance rose to 15,000 in knocks, there were three less kickbacks.
I understand that there are good places for advertising wedding salons, home appliances stores and children's toys.
Should I use cold calls?
