Do not promote them, well not until they give full disclosure and we hear from the top brass (the owners) that they will stop all their funny business.
GSN used to be owned by good honest folk. We did really well with them and had a great relationship. At that time we did not promtoe Vegas Partners for NUMBER of reasons. Then they bought GSN, We stopped promoting GSN immediately.
If you are stuck finding a good casino to promote, try G3 Partner. I have a funny feeling its the old GSN guys in a new guise.
