I feel I see a lot more spam on mw.org pages that have Flow enabled then on mw.org LQT pages. Since so much of the blacklists etc are shared, there must be other reasons why the difference is so big.

My first idea is the inclusion of wpAntispam hidden input in the normal editor (which is reused by Lqt). We should probably gather statistics about how many edits are rejected due to this field, and if it is worthy to include this very simple technique into Flow.

Backup ideas I had if this turns out not to be the reason:

• Could be the simple presence of the form + textarea + submit combination on all pages using Flow. Lqt doesn't have this, which might cause bots to not find it an interesting target, but Flow is tastier ?
• Add to this the fact that Flow pages are allowed to be indexed and crawled by robots, unlike the action=edit page. Explains why if the above is true, we are not being hit so much by this on normal edit pages ?
