Perfect way to detect a bot is when you receive e-mails and there's an apostrophe like in the word "I'm". Once the same message gets rehashed (copy and pasted if you will) It starts to lose integrity. The 'I'm' starts to look like 'I''''''m' or 'I'&&#%m'. This happens all the time. Basic rule of thumb, Is the girl hot and young? Then It's not really her, it's a dude sending the message. Does the girl have cam messaging? Then it is her, but she's paid by the company to make money for the both of them. Is the girl quite older or have fugly looks? Then yes, it's legit.
