https://www.google.com/search?q=draconian Has the word "excessive" in the definition. I think it's at a minimum connoted in most applications of the word. Anyway, it doesn't matter how it's defined, I was only trying to understand whether the OP meant "excessive" or just "something I don't like."
I choose the word draconian because I thought it was the best word to describe the idea I was trying to convey. If I had to rephrase, I suppose that all of 'strict', 'harsh' and 'excessive' would be fair words to use in describing it.
As to your original comment, it can be both draconian and effective. The requirement could be that in addition to your facebook account, you also must upload a photo of yourself, holding government-issued ID, standing in front of the store, etc etc. That would make it even harder to use the wifi anonymously (abuse their system), but would clearly be a draconian measure.
