Forgot to answer this one, thanks for the suggestion I will definitely keep the suggestions in mind. And you should probably be on the nominates list too :-)
Not sure it would prevent these kind of issues, wouldn't it be possible to create a new spam account using a different e-mail address? Unfortunately, if someone is determined to spam, I think it's hard to prevent.
Maybe the best way would be to give admin access to a couple of trusted and regular users, so they can delete / rename stories if required?
Agreed, this is getting really annoying.
I deleted the account a couple of times already, they always recreate a new one... I also banned their company URL but they post summaries linking to their company URL on various free blogging platforms, and post this link instead.
Talk about lack of ethics...
As always, sbruchmann is correct :)
I edited the title for consistency and clarity. Users posting news can edit link and title during 15 minutes, this delay could be increased slightly if required.
