I'd been running a set of 16 long and unique comments across all of my accounts for about 8 weeks absolutely fine until a couple of days ago. Now, some accounts haven't been able to comment for days, others can only manage 50 odd comments per day. I'm sure this is all due to some form of temporary comment banning, but I don't know what has caused it. My only solution is to re-write all the comments, and make sure that each account is using a different set of comments - but this will take a lot of time. I've tried increasing the comment delays and it hasn't helped at all. Anyone got any ideas?
