Is the best thing to do just ignore or should I change my hobby cell / e-mail?

Seem to do.

along with that self patterned hand print on the back of your shoulder.

While no one should have to deal with "stalkers" you have done a fine job in making people not like you. I don't think that you really need to be told that.
Ones mouth is always fatter then his wallet.

This alleged "stalker/s" will eventually go away if ignored long enough although if this person/s actually exists you have done a fine job today by posting this and exacerbating the situation.

It takes a certain level of healthy self image for others to respect you. Others will respect you only when they see that you respect yourself.  

There are situations like this where the sites like TER and P411 can help, but only if that person is making threats for a good review, to tell your wife, etc. They won't intervene if this person is just a danger to you because that is not their business, and if they policed every nut job we run into, they would never sleep.  

Thank you London.

I think if a person were serious about avoiding negative contact, they would STFU & disappear.

I just love it when you make sense.

with a video camera...Is that wrong?
