Soulframe chats have the ignore function implemented for a quick and easy fix! To ignore users in chat, simply type: /i username.
Repeat this process to remove the user from your ignore list. This should be the first thing you do if someone is bothering you in an online chat.
If you notice users constantly spamming, using language that is offensive, harassing, or life-threatening against you or your friends, report them by right-clicking the user's name and selecting "Report Player" then select the appropriate category. Make sure to provide all the relevant details.
