I got and email from a guy a day or so ago asking me to remove the name of his site from my sites title tag or one of my sites or else he will take legal action against me. I told him to go ahead and be my guest. After that, he sent a more conciliatory email saying okay, sorry about the initial heavy handed email but could I remove that word from my site's title tag. I say yes, on one condition, he should remove my site/product's name from his site's title tag as well. The interesting thing was that this guy actually inserted my site/products name in his site's title tag months ago, when I saw him doing this, I paid him in kind. There could be a gap in my knowledge but is there a law that prohibits you from using certain word in your site meta tag?
