and when I block their calls they don't even show on my phone.  

At least it doesn't sound like he is escalating as he's been doing the same thing for a year as you say.  

I would suggest you just keep doing what you are doing which is COMPLETELY ignoring him, which I hope is what you are doing. Eventually he will give up and go away. Unless of course he does escalate at which point it would be time to get LE involved.

Send over Moose Mangler and Louie the Pipe.  He won't call again . . . . . and no one will ever find the body.  Problem solved.  

how did he make you feel uncomfortable?

Just wondering, to see if I'm borderline psycho.

 
if he calls everyday, he's beyond borderline. that's full blown

I leave him voice mails can't get to phone getting high hard one so f off. But that's just me love pushing buttons it would be so fun.

Evelyn: I should've known you'd never do anything to spoil it.
David 'Dave' Garver: To spoil what?
Evelyn: What we have between us.
David 'Dave' Garver: We don't have a goddam thing between us.

 
Get off my back, Evelyn.

...it IS NO question that this dude is psycho.

that could be a win win ...  
as long as you feel safe, ignore him as it seems you have.  
We're you that good or was he that bad?

...then you pretty much already know.

I've noticed it isn't frequency of messages/calls per se that makes a client" psycho" but moreso the timing of the messages and the content that tips off alarm bells.
