To add to what Paige has said I know several ladies who I have talked to about Eros over the past few years and from what I understand from a providers viewpoint it has gone downhill.
Repeated refusals to place ads based upon their photo guidelines yet you can not actually find any "photo posting guidelines" on their website and you receive no response when you request what said "guidelines" are from Eros,
You can find some websites from photographers who can't tell you what Eros's guidelines are (they don't know either) but will show you photo's of what was, and wasn't, approved. It's a bit entertaining when you see what was approved and what wasn't depending upon the ad. There's a bit of double standard there.
(Do you own research if you wish to know more)
The prices vary depending upon location and it is always very high for even a standard 15 day ad. God forbid if the provider wished to be posted as VIP or have extra options on their ad.
Very slow response time to direct contact concerning questions about their service, not just hours, but days or none at all.
I won't tell a provider how to run her business, but I will say that since I started in this playground Eros has definitely gotten worse, from a monger's viewpoint alone, and would rate it lower as far as a "go-to" website for our mutual activities.
