If you're serious about your writing, you probably use the resources of Preditors & Editors. They've been around a long time and have helped many authors steer clear of unscrupulous agents and others who seek to take advantage of writers.
They're being sued now because of their stand against a publishing company. Go to their web page, read about it then do your own research yourself about the company involved. Make your own decision about the matter.
Then follow the link above if you wish to donate to their legal defense fund. Just find the icon on the page that says DONATE. I just made a donation. I hope you'll see fit to do the same.
