Someone is threatening me to file a DMCA with my host, over a "Recent Activity" Mod, that I rewrote completely. It is a free. The functionality is only similar.
Also over the style of the site, this person and I started the site together, everything was implicitly said to belong to the domain. I owned the domain, then this person, decides to brake up and start a whole new site, he has taken all our users, posts, threads, personal data, everything. I recreated the original site then.
I changed the style background, parchment, header, etc. And he claims the style is his.
What do you suggest?.
