People on FP were talking about moving over to Wattpad because (at the time) it was so easy to steal from FP. It was literally you could cut and paste the work. So for grins and giggles I searched a couple sections of my book here, thinking no way I’d find them, and found the person stole the entire first book of my series and two shorts that would become the basis of the sequels. They even had all my author notes.
Plagerists aren’t very bright. They honestly think they won’t get caught, you can look at this situation as a prime example since she stole from some really big romance authors.
One problem currently on wattpad is people “converting” books to fanfic. They take someone elses work and change the character name to some celebrity and call it fanfiction. I’ve had several of them removed. Some I can’t do anything about because the books aren’t published so only the original copyright holder can report those. Unfortunately I don’t have the time to track down the original owners to get them to report it.
But in spite of it happening so often you really can’t live in fear of it. Stopping your work from being stolen means never writing it in the first place. Your laptop can be stolen and someone publishes it from there, it can be stolen from Wattpad, Radish, and other similar sites, it can be stolen from book shelves and someone takes the time to retype it, and it can be stolen from Amazon. If it exists, it can be stolen.
