I read the article which was a great read(Did not find it long at all) and answered the question. However, the campaign itself needs major changes to the rules in my opinion.
- Disclosing the location goes against the very nature of crypto which is why the rewards need to be worth it which they clearly aren't.
- The pay rate of 10 cents per post is way too low and needs to be increased to something more reasonable.
- Posters cannot post a minimum of 20 such posts per week since this is not your average campaign.
These are some suggestions from my side.
