In terms of the ads on oasis active I did find them somewhat distracting with banner ads on every page and some quite strategically placed below search results so they were quite easily confused with actual results.That said it is free and someone has to pay the piper.I found if you spend the time to set-up a comprehensive profile and (as with all dating sites) add quality pictures it is money well spent.I was particularly impressed with the amount of people taking this online dating thing so seriously with lots of comprehensive local profiles to choose from with pic, interests etc.In oasis actives credit they have designed the site to minimize this risk as best as possible.
Generally people not paying for a service are not going to take it as serious.
There are many very nice, honest, intelligent and successful people out there who could make very good partners with you however may not be as photogenic, poetic or quite frankly as attractive as you would like them to be.
It is very easy to be critical when you're browsing through a long list of profiles but you may be your own worst enemy.
Oasis Active does have a live feel with most of the emphasis it seemed on the live chat service although it was a little clunky and difficult to manage multiple chats.
It did have an ‘approve or decline’ contact service which was at least one layer of screening although a little frustrating if you initiate the contact.
