First of all, posts that contain value will gain more likes than just method threads, so to just farm likes, it's more time-wise to just comment on other member threads and provide value there. Add some humor, sarcasm, and memes - it will boost engagement and skyrocket your reaction score. Or just wait for weekends and post as much as nonsense as you can.
Secondly, if you have a problem with someone sharing value and gaining rep in return, you have to work on your personality, immediately, because such a level of toxicity will lead to nowhere in life.
You clearly don't see this yourself, I will be kind enough to point on that you look incredibly dumb posting here after many members have confirmed that this still works and they are using it. In addition to that, there were screenshots posted of spammy comment examples with adult CPA links few pages ago. If those spam links can be posted and they stick, anything else can be possible for sure. So, please, bite a wall.
I'm still receiving profit from what I did a year ago, shared all proof here about my earnings, campaigns and went deep down on answering every damn question here. If you think that this was because of some sort of planned manipulation with newbies, please add some of your salt on that wall.
Finally, if you cant get this method to work for you, it's not an end of the world, it's just that this might not be a good method for YOU. I've noted that you have some skills in PPI, scale that, do not try to focus on methods that do not work for you. But do not expect your results to be the same for everyone else. And don't get salty when others have success where you failed, instead try to learn from them.
