I think this is something that would have to be implemented in conjunction with Lithium. There is a problem when people enter phone numbers or account numbers onto a searchable website. They could end up getting nuisance calls or worse.
Would it be possible for the software before accepting a post remove 9/10 digit numbers which start with a 01, but are not 08 numbers.
It would stop people having to edit their posts so much and make the forums a safer place to post. Similarly, account numbers (all starting with LC) could also be auto-blanked/not accepted.
I know it would be a hassle, but it might help some people who aren't so web-paranoid or quick editing their posts.
