I tried to add a comment to a talk this evening, which was perfectly innocent, however on web2 it was rejected as spam. Tried it on the legacy website and the message went through fine, which is a bit strange as I believe they both use the same API?
Steps to reproduce:
1/ Login (I logged in via Twitter as myself, but presumably that doesn't impact it)
2/ Browse to talk
3/ Rate the talk as 4/5 and comment: Plenty of nice little 'take-aways' and tools to check out - would have been nice if it was a little longer, but still makes me want to start using Magento 2 for all our production sites now!!
4/ Try to submit
The review is posted
Error Message: Comment failed the spam check.
System: Fedora 21 running Chrome 48
Note: I was using hotel WiFi.
As far as I am aware, the spam filter is running Akismet, but that doesn't explain why I could post it via Legacy, but not web2
