All I see in your screenshots, is that a rogue has beacon of light in his buffs which isn't bannable and tbh your screenshots doesn't prove that the rogue is getting healed anyway. Also, make sure that if someone would get banned in such case the violator would be the paladin since he is healing the rogue so he is the one who abusing.
Developers are already aware of this bug, please wait for a fix.
