You are both off topic
But as you raised bounties and mercs
Mercs have never had a requirement imposed on them to declare openly to their prey.
Read the server rules here ...

I can remember quite clearly SL clan never did this - they just did the job and dealt with any consequences afterwards.
Most of the time there was not any consequences as people recognised their rp
And they definately were not KOS status for any server clan because of their work.
And bounties do not only have to be places on the bounty board.
Anway a consensus and discussion about revising merc roleplay may be best here - if that was even the problem here - but I dont know that at all.
