This question had been put on hold with the reason:
"Questions must involve real code that you own or maintain. Pseudocode, hypothetical code, or stub code should be replaced by a concrete implementation. Questions seeking an explanation of someone else's code are also off-topic."
where the only "problem" had been that the OP added one method to the class which isn't in the real code.
The OP stated in the comments of a now-deleted answer:
"PadUsername does not belong to this service": And in reality it doesn't. I just integrated the method for sake of readibility.
The OP should have stated this in his question but it is IMO ok like it is. I think that closing the question only had been triggered by a comment to the question but not because it is example/stub code.
I understood the reasons of the linked meta answer, but none of them apply to this question.
What do you think about this?
