Same here, I wasted a delegation on the project unfortunately. At some point I noticed they were simply upvoting one account at 100% twice a day, and even after I asked if I had to keep my delegation and if the 'tiers' they promised were still in place, they kept saying 'yes all will be rewarded as per originally promised'. Currently they're powering down the few SP a week the account is worth thanks to their curation rewards :-/
