It's like you unlocked a secret for those seeking merits to rank up and I won't be surprised if some new accounts could be flooding their thread with edited pictures of sportsbet in their phone in the next few days hehe. Seriously speaking though it's not like they are sending merits indiscriminately in their own thread to be considered as incentivized posting.
Getting merits on Bitcointalk should come from genuine contributions. Instead of sharing edited pictures, engage meaningfully in discussions. Quality posts that add value to the community are more likely to earn merits.
