Hypothetical question

Quick background on my situation — any input appreciated.

someone copied my website design. I've been dealing with this for about 11 months now and the situation isn't improving.

Has anyone been through something similar? What worked for you?

Illustrative response

Just want to point out — the statute of limitations might be a factor here. In some states it's as short as 1-2 years. Don't sit on this too long.
