You are not required to fill out your profile nor upload a profile photo. Even without these, you can freely access the casual dating site.
However, if you want to match with people and have other members contact you, a comprehensive profile will attract more members to visit your page.
Likewise, when you upload a photo to your gallery, this can show up to other members' newsfeeds, which can help instigate a conversation through the comments section.
This is a free mode of communication on the dating site, so it can help you if you're a standard member.
It's not essential to upload explicit content to your profile, although this could increase your chances to find a partner that can fulfil your sexual fantasies.
As you already know, the site is meant for finding hookups and casual encounters, and flaunting your assets can help you more than it can hurt you.
If you are just a standard user, you won't be able to see the full profiles of the members. What you can only view is partial information when you hover or click on a user you find interesting. You are also able to see if that user is a premium and/or a verified user.
Once you hover on a profile photo, the preview will appear in a boxed window. The window includes a few thumbnails of that member's uploaded photos, username, age, location, and gender.
It is also indicated there what that person is looking for on the site: whether an encounter with men, women, couples or groups. A short preview of the user's about me paragraph is seen too.
Aside from this information, contacting buttons such as Flirt, Hotlist, Add Friend, Message, Send IM, Tip, and Send Gifts are also available for quicker access.
Most profiles on SwapFinder are filled with naughty photos. A lot of members use explicit content for their main profile picture.
Unfortunately, you cannot filter out members who use graphic images. When you sign up on the site, be prepared to see explicit photos.
