I think I can connect to this "external forum" you have posted since I vaguely remember a thread very, very, similar to this, and if you happen to be the same guy I just don't understand why you didn't read the responses because those explained everything pretty well.

Let's start with simple thing, and keep this in mind: "Why would I care? Why would anyone else's doings affect me?"

Someone runs a parser in raids because he has very high drive to improve himself (because he enjoys it), he doesn't harass anyone else over it, mostly keeps the information to himself and at the end of the day to him it's just visualization of how he has improved over time.
So OP, based on that what description, would you see any reason to ban him? Would you also ban his close friend who plays on PS4 (aka. doesn't have a ACT)? You probably wouldn't, and SE definitely doesn't.

Now here's the thing: Absolutely no one ever has been banned for USING a parser. People, however, have been banned for HARASSING other people over their performance and the key word here is "harassment" because there is no difference in harassing people over their numbers and telling them to harm themselves in terms of what you get as a punishment.
People openly use ACT during streams and SE has done 0 anything even though they follow stuff like Savage/Ultimate world race so they are absolutely bound to see people use it openly. They know about it and do nothing, take that how you will.
