A lot of people lie on their life.
Probably for protecting their life i suppose, but some are doing this for the game or just to put down someone if we want to be rude or even take their revenge in game because they hate their life.
In this kind of game, people must never forget that a lot of people aren't what they say.
The gender, the age, their job etc etc
Some women lie on their age because they want return a little in their young age. Guys too
Some girl in game are guy, some lesbian are guys (often to have more chance with girl and reject men but when we know that a lot of girls are guys....^^), some guys are girl too.
And about picture, they are a lot of fake pictures, trading pics and other. It's for that that i don't care really about picture.
So it's true that if the "real" join the rp, it can be more excitation (about the âge by exemple). But sadly, a lot of people lies, so people should protect themselfes and not believe people easily.
In my case, i don't lie because i hate that but if i don't want speak about something, i say it, it's all. I prefer someone who like you for what you are and not for what you aren't.
Even after a few month or even year specially when the relation is only virtual.
In rp, i take care more about the link betwen the player, the chemistry between them.
So take your time, take some distance a little to protect yourself and if after some time you can't definitively retrieve the rp relation, stop all. And don't forget in future that people aren't what really they pretend to be.
