I love Squarespace, but their spam-handling tools are abysmal. Supposedly this will be addressed in an upcoming release but so far there's no word on when that release will be.
As a result, anyway, I have to put ALL comments through a moderation stage where each comment needs individual approval (ugh). Time-consuming and a hassle, but it's either that or let all the spam comments through...and there have been a LOT of spam comments which I've had to block.
I've been a bit behind in comment moderation but have caught up now. Apologies for anyone who has been wondering why their comment hasn't been posted!
