Based on the activity visible on your GitHub profile, I understand that you are BlueFinTuna.
I was surprised by your response. It appears that this pattern of commission changes has been ongoing since 2024 according to onchain data, and is now being justified by the fact that other validators engaged in similar behavior or that the ecosytem has UI limitations.
Participation in ecosystem validator programs such as 1KV is voluntary. Given the information asymmetry between validators and nominators, repeatedly adjusting commissions in this manner raises legitimate concerns about alignment with community expectations.
Validators who benefit from special roles or privileges, such as invulnerable positions, are generally expected to operate under a higher standard of transparency and integrity than the minimum required by protocol rules.
Considering that roles such as system chain invulnerable positions @OliverTY and participation in Paseo Network @alejandro appear to be granted rather than fully permissionless, it would be reasonable for the ecosystem to review whether continued participation under these conditions remains appropriate.
It appears that these behaviors have been discussed for years across multiple validators but never properly resolved. While improving the UI and nominator education may help mitigate some of the issues, I am increasingly inclined to believe that protocol-level changes are necessary to address this problem definitively and prevent it from resurfacing.
