Just lost my main.

Yep. First Sythe trade and I rushed in headfirst. Lost my main and only account. I chatted with the scammer on a website with a chatbox, is there any way to recover the conversation?
I have PMed him and if he lets me buy it back I have promised I will not report him, and I will stay true to my word.

 

You shouldn't have much of a problem recovering the account through Jagex if you are the original owner.

However, as far as the report, we cannot accept conversations from chatboxes on other websites, as it would be extremely difficult to prove that person's connection to a Sythe account. Moreover, we cannot accept logs/convo histories, as they are easily edited.

For a ban, we really need screenshots of an active MSN/AIM window (essentially, anything with a distinct address.)
