Lets start from scratch: I run
I want porn! - a website I coded entirely line by line myself (except the Joomla-backend)- since May 2014.
And there is "theporndude", who claims that I've cloned/copied his site. There are a lot of porn directories out there and the I've seen this column-design first at TBLOP and definitely not TPD.
So for me this is ridiculous, but he already convinced himself and I guess there is nothing I can do to change his mind on that.
Actually I'd give a fuck on his opinion, if he would not contact other webmasters to
cancel established link/traffic-trades to my site.

We increase traffic all the time, but he has a lot more - And so he holds the whip hand when he forces them with something like "Remove the link to Iwantporn or I remove mine to your site"
There are more porn directories/linksites like that (where I think mine is the greatest of course ;), but it seems he is only concerned about mine. So I guess I do something right. ;)
I also have a lot of conversations with various webmasters, where some set my link back when they heard the story from my POV, but I guess I would have AT LEAST twice the traffic without his efforts.
Anyone had something similar? How do you get rid of such a disease?
