Seeing a girl and each going your own way is common. However, some girls don't take that too well. Sometimes girls will go on your Tinder profile, and use the Report feature, making something up.

On Tinder, having a user or users report your account can either result in two things: a hard ban (usually because you did something against Tinder TOS), or what is called a "shadowban." Tinder doesn't care if reports are real or fake. If one or more people report you, they'll restrict ("shadowban") your account, by showing you to only 90-99% of users. However, they don't tell you.

Solution: unmatch girls on Tinder a bit after you have their contact details or go on a date. Crazies/immature girls can't abuse the Report function.
