I use several messagong apps. I use Viber, WhatsApp and Hangouts to communicate with people I know. I added people I know via their phone number or Google IDs on Hangouts. I use Line to share my photos and videos, but I have only two contacts on Line. I also need to know someone’s phone number to add him/her on Line. There are some problems on messaging apps. I found many fake accounts on Tango (I can search users without knowing their phone numbers). Some of them are scammers and others want online sex. It is hard to find someone who is not fake on Tango. Iwas chatting with a girl who I found on futurenet.club on WhatsApp I saw her phone number. I added her phone number in my contacts and started to chat with her. She suddenly deleted information from her profile. I started to chat with many people on messaging apps and after a few messages they stopped communicating with me. We represent ourselves and then we stop chatting.
