Well I may not be in any of these countries, how ever I first joined this site do to an ad on the site Advanced Anime which reaches a very diverse group of people from all over the world. Might I suggest doing this to other sites that also reach over a large scale ? If you think this is a good idea, I'll gladly post a list of sites I use that have a large enough member base that you will get more people through advertisements.
Sure thats no problem:
Advanced Anime has 307,094 total members. Actively getting around 70 -229 people online on any given day. (I used to see your ads all the time, now it is less frequently)
OtakuCenter has 38,000 total members. How ever they get a lot more people viewing a day, at the time of this post 709 people are viewing the site not counting myself.
Sankaku Complex gets hundreds of posts a day from dedicated members and guests, while this site is made for people 18+, it has a lot of hard core gamers, that love this type of thing.
Gaming Gutter is another one having 63,288 total members. How ever people on that site are rewarded on being active and has many game threads for maple story and the works. So this would be another game that they would get hooked on.
GameSpot is pretty much self explanatory, every person I know has or currently uses this site as it is a huge game rating, review, and low down site.
All these sites I am a members of and can vouch for the activity level and diversity of people. I can name a few more if it is necessary or wanted. Tho I feel that these are a great starting point.
Try advertising in youtube and sites that has online anime videos like gogoanime, crunchyroll, etc. We usually(pinoy anime lovers) visit those sites. Y8 and online game sites are also good fishing spots too since many visit these sites as well. And I hope you guys sell credits as prepaid cards here in the Philippines because UGC is not cheap and easy to acquire.
