Now I've not looked up enough caselaw on the fed level as to what harassment is.
eeoc.gov has:
In general,
teasing, casual comments, or single instances of inappropriate conduct are not illegal. For inappropriate behavior to rise to the level of illegal harassment, it must be unwelcome or unwanted. It must also be severe (meaning very serious) or pervasive (meaning that it happened frequently).
The scope of EEOC is outside of Patricks situation.
Closer to his situation.

(B) the term “
harassment” means a
serious act or
course of conduct directed at a
specific person that—
(i) causes substantial emotional distress in such person; and
(ii)serves no legitimate purpose;
Laughing at Patrick I'm gonna guess isn't a legitimate purpose. But telling someone about his past VS his present position might be found as legitimate. Especially if the response lacks farts, Jennifer, toilets or whatever....
As to fucking himself comments on phone harassment via quora include:
How many texts count as harassment?
Do not text a person if you have texted them
twice or more times without a response. This will be considered harassment, especially if these messages are sent over an extended period of time.
How many calls is considered harassment?
If the person being called doesn't want the call in the first place even just
one or two calls can be considered harassment. start by blocking their number. if they find another way to contact you block them. at some point you may have to consider a restraining order.
Like Jackie trying to pick fights with the swatters Patrick is screwing up enforcement opportunities with his conduct.
