Nope this is not, most of the scammers send you their websites that look like Pokemon Reborn or has a page asking for your password in return for cheats.
These are obviously fake and the scammer will steal your password.
This form of scamming is mostly seen in PMs, if you see one please immediately PM a member of staff or 'CruZ' (recommended).
From there I can take legal action & report to the local enforcement agencies to stop this from happening again.
