If you are a clan leader, you are responsible IC/OOC for the members of your clans, because you choose who is in it.
If you belong to a clan and you have issues IC/OOC with other players, take them to your clan leader, and they will deal with the respective clan leaders.
Clan leaders are like fathers, teachers, mentors.
If you don’t get help from your clan leaders, change clan leader, or form your own clan.
