Spam from India

I removed the comment, which was not spam, as it didn't contain any links.

Wikipedia reports that spam posts

... may contain anything from a single link, to dozens of links. Text content is minimal, usually innocuous and unrelated to the forum's topic, or in a very old thread that is revived by the spammer solely for the purpose of spamming links.

It seems to be the same criteria used to identify spam posts on Drupal.org.

The reason to be more restrictive about what to consider spam is that spammer accounts are automatically blocked, while users who created posts (or comments) that are not appropriate are warned (the first times).
A definition as trash that shouldn't be posted is too generic, and would include the posts of people who didn't know exactly where to post a comment, in example.

I agree that sometimes some trash posts are created from spammers just to verify the action that we take on such posts, but until a user doesn't actually create a real spam post (or the user has already spammed other web sites, and it seems he is starting to spam Drupal.org as well), we should not block the user account (IMO).
