A user can stake dust amount for themself or other community members. If the user commits offenses, the intended behavior is if I have staked GTC on other people, and I have misbehaved, then all my stakes on others will be slashed. Also, if the stakee commits offenses, then those particular stakes will be slashed.
Both scenarios mean that the staker -> stakee amounts will be slashed regardless of whether the staker or the stakee commits offenses. When staker takes dusts amount on multiple stakees, or a stakee has many dust amount staked by other, this will make the required slash() flows more expansive due to dust value updates.
