I want to say you were warned
this is a risky path to travel on a couple years back.
Considering you went on to remove any trace of implementation details from a bunch of other posts asking for help how to do this, presumably to protect some kind of competitive AH advantage, I find it a little ironic that you are now back asking for help and providing source.
All that aside I'm sorry you lost your licenses.
I looked at the python code and the addon and I can say it's all up to interpretation whether what you're doing is automation or not.
If you were using an external program (ie AHK or similar) to reload the game to get new addon data your python was generating or to click your bid addon button, then it's out of the grey and few miles into the black.
