Apart from the popular social networks, there are social websites meant just for meeting and talking to someone new.
3 popular and effective websites are: Plenty of Fish, Ok Cupid, and (where you can meet someone that has a similar taste in music as you).
Most sites allow members to upload photos or videos of themselves and browse the photos and videos of others.
Sites may offer additional services, such as webcasts, online chat, telephone chat (VOIP), and message boards.
In Germany government financed NGOs like "Verbraucherschutzzentrale" sometimes help to sue online dating sites.
