im basically giving free advertisement, since I keep forgetting to do the 10 posts in the gambling section...lol... I find it hard to post there without it being spam since it is mostly marketing for people's online sportsbooks and casinos anyways...
Honestly, I didn't sign up in the first week coz I thought I'll struggle with '10 posts in Gambling' requirement. But in the last week I've done over 70 posts and almost half of them was in the gambling section.
It's way easier if you actually use any of the gambling sites, then you can engage in subjects/discussions that interest you, it all goes naturally with no need of spamming.
You don't necessarily have to gamble, you can just play with small amounts (use free faucets) or try investing or earning via affiliate program (putting tracker link in your sig is a good start).
And if you don't see any threads that you can contribute to, you can start a new one yourself.
