Suppose there was a user of one of these sites whose handle was
Won't. How would one form the possessive of this username to refer to that user's post?*
Given that the
's possessive construction is apparently derived from a contraction, and the existence of a fair number of double contractions, I suspect this first one might be correct, but frankly, it looks weird to me.
One apostrophe in its usual place looks a little better to me, but it also looks like it might be a pluralization,** even though that doesn't make sense in context. This choice might read confusingly.
This seems to be a non-starter, since it changes the name for the sake of forming the possessive.
Is the first one right, or is there a possibility I've missed?*
*Aside from using "the post by Won't" or similar rewriting.
**Especially given "Do's" and "don'ts" or "do's" and "don't's"?
