If you're accusing someone, you better provide some evidence. This is some serious allegations (although I'm still not clear what you mean by "groom me" exactly).
Thank you for stating that more strongly than I wanted to. I hate to say it, but just based on what OP wrote it seems like a giant leap to think that because of a single PM someone is "grooming" him. That's also why I want to see the PM, but I'm not even sure if OP is going to come back to this thread. It is indeed a serious accusation.
Ugh. OP, that's the kind of stuff you might not want to post anywhere on the internet, and I'm not even talking about attracting perverts (though that's part of it). If you're at school daydreaming about being online gambling, I'd say you've got a problem that needs to be dealt with sooner rather than later--plus I'm pretty sure it's not legal for you to be gambling at your age. You're just going to attract all sorts of negativity, and your words written on this site are permanently linked with you if someone knows your real identity. I don't even want to know how you get money to gamble.
OK, I'm done being the stern random internet father figure. Lol.
