Maybe just don't edit Wikipedia pages, then you won't get banned. Wikipedia doesn't like people vandalizing (un-constructionally editing) the articles on it. You only got banned over-and-over because you were violating the editing rules on Wikipedia.
If you actually obeyed the rules, you wouldn't have been banned in the first place. Wikipedia doesn't wrongfully ban people, they ban people for vandalizing articles.
They might be tracking your login and out times, or writing style. I can tell who's code belongs to people at work, it's like a fingerprint. Maybe change the topics, writing style and login/out times.. good luck with continuing what you enjoy
