If you still have an account on SXC and regularly receive requests and information about photo use originating from SXC you can do as I do. Answer together with some info about RGBstock.
Be a bit careful about what you post. They can read, too, and may decide to take action that would stop that.
However, it's a great idea.
I contacted everyone I knew from permission requests I received.
I made too many comments on photos about rgbstock and they cancelled my account without even contacting me. I got axed!!
As long as you do not post over the sxc server and only re-direct people when they took the first step in contacting you in your return email to RGBStock for the use of one of your files it will be okay I guess.
I wish both up- and downloaders well using any resource site of their choice. It is hard to break with old habits but once people experience the difference there will be no stopping them. ;-)
You are right and you can help!
I always do it Lars!
Something else that can help is subscribing to RGBStock's Twitter and Facebook feeds.
This will increase the exposure of RGBStock and it will help with the search engine ratings.
I dio it too. I just send it through the requests. I haven't gotten shut down yet, but we'll see.
I Buzzed RGBStock to all the peepz I'm following and to the ones that follow those :D
