The banned users have taken to social media to express their frustration at having their accounts suspended, with many believing that they're being discriminated against because of their gender identity.
The app has a 'report' function, that gives all users the option to flag inappropriate messages or photos, bad offline behaviour and spam accounts.
It appears that transphobic users are misusing the report function to alert Tinder to the accounts of transgender users, who subsequently have their accounts locked while Tinder investigate.
In a statement about the banning process, Tinder said: "Each banned account is individually assessed. If we find that a user has been wrongfully banned, then we ‘unban’ their account."
"This includes instances when transgender users are reported by others, but haven't violated any of our community standards."
Tinder currently only has male and female options for users to select when they sign up, and there's no feature for trans preferences. A spokesperson for the app said: "Unfortunately, [only being able to select male or female] can lead to some users reporting other users when they unexpectedly appear in their recommendations."
"Tinder recognises and believes in the importance of being inclusive of all gender identities and is working towards optimising the experience for everyone."
It's hard to imagine anyone going as far as reporting someone for being transgender, but according to Twitter, there's a huge number of transphobic people who think that it's ok...
