In 2016, there was a record number of offences related to dating apps - with 50 sex crimes involving Tinder and Grindr being reported to Scotland Yard in the six months to June.As it is easier to steal a card from the USA they write in their profiles that they are from the USA or some other European country. Be careful if a woman decided to visit you after several days of communication, if she is writing that she is already in Moscow and trying to buy tickets – this is a scam (Moscow scammer group). Do not send money for buying tickets as all tickets can be bought online and you can send online-tickets to the user. There are no such contracts with an agency when somebody is obliged to buy tickets in this agency, it is scamming. There is no requirement to show cash money at the customs.Customs deals only with the import of prohibited things.If you pay the site a fiver with your credit card or on Pay Pal, it will search the depths of the popular app for a specific name, age and location.The Sun Online tried it out for authenticity - but it only appeared to work in some cases.Daters can swipe right to "like" a profile and left to reject it.Two people who have "liked" each other's profiles are deemed a match, and can beginning messaging via the app.Scammers are often detected within 1-2 days after registration and they get deleted. If a woman wrote to you as it was written on the dating site from your country, but later she appears to be from Russia, Ukraine, Nigeria then yes, it is a scam.Yes, “women” can have different explanations why they registered from another country, but mostly those are excuses.If there is already a visa on the hands, no money is required anywhere, only tickets for travelling. Sometimes the scenario is different: women do not ask for money for tickets or visa, allegedly they are coming to you at their own expense, but they are bringing some rare, old or expensive thing as a gift with them, customs stops them and wants money for it. Nobody would bring some very rare or expensive present for a first meeting. When you receive a letter with notification about a will of a late person whose name you hear for the first time, winning in lottery that you never participated in, request to help load money to the account of a stranger or export-import gold for a reward – this is Nigerian scam. Sometimes you start communicating with a woman, she has beautiful model like photos and she writes you wonderful long messages in good English.After several messages it appears that she does not speak English, all this time she went to a dating agency who helped her to translate her letters, but now she does not have money to pay for translation and you need to send money to this agency in order to keep communicating with her.
