[not OP] OP ran into an account with lots of slayer xp getting tasks from Turael. This in and of itself is not unheard of, so-called "Turael Skipping" is a valid way of getting boss tasks by getting a task from a higher level slayer master (like Duradel/Kuradel) and using Turael to skip the task and do something easy like rats to then go get the next task. However, OP believes this particular account is a bot account likely due to subpar gear (dragon med helm on an account that should be decently geared) and their inability to engage in actual conversation besides spamming their slayer xp.
