Regarding the negative (historical) trust, unfortunately for us, there is no formal way on bitcointalk to open a dispute or request re-evaluation. One person who have rated us negatively passed away (RIP) and the rest are either inactive or do not reply. So, looks like we will have to keep moving with it and just keep up with hard and decent work.
And regarding small races - yes, the prize pool is small atm, but we will change it soon, and for those who want easy (although smallish) win now - welcome. But be sure we will make our $500+ Races regular.
The other one that give you negative feedback is long time inactive since 2018 it's impossible for you to negotiate to him even you tried to message him many times as long he will not visit this forum he will not read your message .
There is a chance in 2 other dt they are still posting but not that active unlike before .
