on Rafferty · 1169· 8mo ago · negative28“Poor product and service”We use Pilot for our accounting service and they require that we use Cointracker to get blockchain reports incl. cost basis. Working with Cointracker has been awful - half the time it doesn't sync correctly, the UX is confusing, and we really only need it for 1 specific job. Maybe we aren't the target user, though, as it seems they may be more consumer focused. Their support and account management is often weak- sometimes replying to me twice from two different places, opening two lines of comms. I've consistently found it difficult to work with and unimpressed with their solution, so decided to vibe code an answer to get rid of my need for them.

The cluster shows clear patterns of sybil behavior and reputation manipulation intended to inflate credibility scores rather than reflect genuine, independent trust. **Related Accounts in This Cluster:** 1.

He has no reviews; I'd be very cautious about this fellow. Would love to be proved wrong but right now I can't recommend anything he says given his support for the @web3 handle and coin link -> https://x.com/Entity100x/status/1945897403183255580

I've known him through many different groups that I've run (pokestonks, niftystonks) and he's always been a solid guy. I've probably known him for almost 4 years now, insane. He was incredibly active and liked in my groups I've also had him build custom dev tooling for one of my groups in the past and would happily have him do it again Motivated guy who traded very, VERY well in NFTs in 2021.

He actually helped me way more clearly see one of the problems we've been dealing with (re: vouches and how people are thinking about them) and I'm very grateful for him taking the time to share his feedback with us. even bigger fan than I was before tbh
