First off, this board is for collectibles. You want digital goods:
https://bitcointalk.org/index.php?board=93.0Also, some pointers:
- mentioning the motorcycle brand name isn't a good idea because you start to run into twitter's 'account squatting' rules.
- They might be able to assert a trademark claim
- Posting it here makes it very clear what you're doing. In the forums where these accounts are bought and sold, they usually redact part of the name so search engines don't pick it up
- Technically buying/selling twitter accounts is against their ToS
I think you're looking for ogusers.com although I really don't recommend going there. Alternatively, use it as your own personal twitter account for a while, and then reach out to the motorcycle brand and don't offer to sell it to them. Rather offer to tweet what they want on a contract basis (and remove your personal tweets, etc).
