I'll preface this by saying I don't know Kirk Fisher, nor do I know precisely what sort of harassing behavior he plead guilty to.

Many people in all 50 states have found themselves in this situation.  Before pleading guilty to any criminal offense, even one termed a "petty misdemeanor," you'd better consult a good criminal defense attorney on what the legal ramifications are.  I personally know of people who pled guilty to crimes they didn't commit because they were under the impression or were assured by court-appointed defense counsel that, "It ain't no big thing."  Wrong.  As a matter of principle you should never plead guilty to something you didn't do, even if the prosecution offers you a plea deal that takes a felony conviction off the table leaving you with "only" a misdemeanor conviction.  Be smart.
