"Asked about R4R in the early days of ethos and admitted now that this was a mistake and does better!"

Appreciate you taking accountability and admitting that it was wrong what you did in the early days. It shows that you are willing to put in the work and use ethos as intended which a lot of other people wont and i have a lot of respect for that. Keep building your reputation in an organic way and you will get more and more reviews coming naturally!
