The recommendation is to temporarily
+r the channel and
+R your own user.
-christel- : [Global Notice] Hi all, we are aware of the current spambot attacks, and we would encourage users to set themselves +R and channel operators to set +r in the channels while the attack is ongoing. While our mitigating efforts are catching the vast majority at the gate, a small proportion still make it through. Apologies for the inconvenience and please bear with us as we do our best to minimize impact.
It's extremely disruptive to conversations. We've
+r in #pyramid and I suggest that an op in #plone do the same until there is a permanent fix in place. Until then, I've left the channel because of the spam.
Thank you for your consideration.
