It is an undeniable fact that, based on on-chain data, several validators (Coinstudio included) have been caught engaging in bad practices, including running validators under multiple identities and performing commission flipping, abusing the system to the detriment of nominators. This has been clearly documented in other forum threads and medium posts.
In your case, regardless of attempts to downplay it or argue that it was done “less” than others, in my opinion the responsibility is the same.
It is not ethical for a validator to advertise a 0% commission for most of the day, only to exploit a narrow time window—when the protocol records the commission that will apply to the next era—to raise it to 5%, 10%, or even 100%, and then promptly revert it back to 0%.
This pattern has been repeated consistently over long periods of time. As a result, validators have extracted hundreds or even thousands of DOT from nominators who reasonably believed they were delegating to low-commission validators. The harm is not only financial, but also reputational, as it undermines trust in the staking system as a whole.

Returning to the topic of this thread, I believe it is entirely legitimate for community members to ask for transparency regarding how funds are spent in certain bounties, especially given past excesses and abuses that ultimately led W3F to intervene and shut some of them down.
In your specific case, Coinstudio operates multiple validators (between 15 and 20 by my estimation) across Polkadot, Kusama, Paseo, and several system chains, which already requires a non-trivial amount of time and operational effort.
In addition, Coinstudio acts as curator for Bounty 31 and Bounty 25, receiving approximately $2,500 per month ($1,180 and $700 respectively acording to their spreadsheets).
Bounty 31 - DOT 
Bounty 25 - KSM
For this reason, your role as curator in Bounty 50 – Infrastructure Builders Program, and the $3,400 per month compensation associated with it, raises serious questions. Given that this bounty pays $85 per hour for administrative tasks, this compensation implies roughly 40 hours of full-time work per month dedicated exclusively to this bounty.
My question is therefore clear and direct:
Please provide a detailed breakdown of the administrative tasks you perform on a day-to-day basis for this bounty to justify the $3,400 monthly compensation, and, if possible, provide verifiable evidence to support it.
It is difficult to reconcile how you can simultaneously manage a large fleet of validators across multiple networks, act as curator for Bounties 31 and 25, and also be effectively employed full-time as curator for Bounty 50 – Infrastructure Builders Program.
Given that this is one of the bounties managing the largest budgets, I believe the community is fully justified in asking for clear answers and concrete evidence to properly assess the work being done—rather than vague or evasive responses, which is all that has been provided so far.
