Personally I'd have a bot to auto-delete any post that has $ before the ticker as in " Interest in $xxxx is higher than ever".
It's invariably a sign that the post consists of cut-and-paste company propaganda and vapid entirely baseless wildly optimistic forecasts which turn out to be utterly false.
