I was being banned because of it.
"Account Action: Suspended until 2020/05/21
Offense: Exploitative Activity: Abuse of the Economy"
That happened after I installed TSM. That was the only thing I have changed with my addons. Perhaps the creation of the shopping-, auction- and sniperlists are not allowed as they are "semi automated" through a macro. They can make you scan the AH and play the market quite easy. When I was asking a GM for a report about the ban, I just got a default mail that was referring me to the Terms of Use and In-game policies.
This was the mail with the reply:
"

After this one, I did not receive a single mail anymore.
