Someone gave you a website, but never transferred the domain name to you completely after more than one request for the authentication key. Later letting the site lapse without telling you losing all content and work on the site?
Someone took said website back for a short time, while you were on vacation, when the opportunity came up to monetize through a giveaway and twitter party. Without sharing the revenue?
Someone asked to review your ebook, using the content to successfully write an ebook, without ever crediting you in any way?
Someone stole your idea and launched a book the same month as you on the same topic?
Someone posted a blog post with your same title two days after you?
Someone launched the cover of her coming book the day after you did?
Someone bought a domain for a website with similar focus as your main blog one week after talking with you about your passionate idea?
Someone later told you on the phone it didn’t matter because “ideas aren’t trademarked and as long as the work is her original words it’s not illegal”?
Someone replaced your affiliate links with her affiliate links on a website you both worked on?
I’m not sure what you would do but blocking and unfollowing were therapeutic for me. A small amount of whining and a passive-aggressive blog post were also helpful. Creating my new to-do list and kicking butt on my new ebook project were even more helpful.
Understand this – there is definitely an ugly side. But you don’t have to fight ugly with ugly! That and there is sometimes a difference between what is illegal and what is ethical – decide whether you are willing to settle for “just legal” or if you want to have a truly clear conscience so that no one can smear your good name behind your back.
