+1 for that, was my primary thought regarding the anti-spam functionality i was referring to. actually had a sort of deep thought about that the other day.
i think in todays landscape on the internet spam is becoming an ever increasing issue and without doubt buddypress sites/admins are bearing in inordinate brunt of that battle. Now that we have lowered the bar of entry there is (if we have our way) liable to be a lot more fresh targets for these malicious interests. Nothing dissipates the enjoyment (by admins or users) of a social network faster or more easily then spamming. Not to in any way subtract from the great strides that have already been made in this regard, we owe it to not only our own community but the internet as a whole to be proactive and step up our game in regards to making these leaches lives more difficult.
