Online dating services allow users to become "members" by creating a profile and uploading personal information including (but not limited to) age, gender, sexual orientation, location, and appearance.
Most services also encourage members to add photos or videos to their profile.
In Eastern Europe, popular sites offer full access to messaging and profiles, but provide additional services for pay, such as prioritizing profile position, removing advertisements, and giving paying users access to a more advanced search engine.
Others utilize the freemium revenue model, offering free registration and use, with optional, paid, premium services.
Still others rely solely on paid membership subscriptions.
Because online dating takes place in virtual space, it is possible for profile information to be misrepresented or falsified.
While some sites conduct background checks on members, many do not, resulting in some uncertainty around members' identities.
Some have a broad membership base of diverse users looking for many different types of relationships.
