I emailed your tread to development.

Closed spam post (possible that not only spam) should be not available for anonymous (for example spider).

@zbik, I only have enough karma to close spam threads at this point in time and currently I do not have the required 1000 points to be able to delete the spam posts. I make a point of weeding through any I find when I visit the forums, however I agree that closing them without deleting them completely is not necessarily a bad thing for the spammers, as they still have backlinks to their websites from the Odoo.com domain. I think perhaps there needs to be a reporting mechanism for spam posts, where those with a designated level of karma can flag spam posts for the Odoo team (or those with higher karma) to be notified this would help immensely. I think if a post has been closed as spam by someone with enough karma the post should then be hidden from view to the public, and spiders. This will help discourage spammers, as from what I can tell at the moment, these spam posts are being created manually. If their posts are not worth the effort they will eventually move on.

Google is a cache hampset... and keeps cached pages for a loong time:) So, i would hope that odoo admins find a way to limit robots from accesing suspicious pages, and agile users to keep this forum clean with prompt deleting of such posts:)

Honestly we as users can do a lot about this. We can prevent them from showing up in Google or atleast push them down A LOT. Every spam thread that I find I'll do the same too. First downvote, then close, then delete and then editie the topic to remove all links and personalia details. This way they will not be able to be contacted and the interesting parts are out of the topic. Honestly everybody should do this.. And perhaps even delete the titles and only leave like one line in the post. This way there will be no good indexing on Google!

Remove content, YES, it is good idea!

downvoting and deleting do not have any effect. Closing a post for reason of spam is enough to keep the user from posting again. And a deleted thread is still anonymously readable and indexable by Google. Deleting the content would help however I am to the point that if Odoo does not care, why should I. Yes I will delete spam but I don't know if I have the sustained energy to edit all that content. This should not discourage others from doing what they feel is best for the community.

Hmm yes it is a lot of hassle for something that doesn't help you a lot but I hate spammers. I wouldn't say they don't care but its probably rather low on their priority list and they got plenty of other work open for Odoo itsself.. So I guess its a choice of priority

Seems that maybe my wishlist issue #3460 might be making some headway. https://github.com/odoo/odoo/issues/3460
