What if the "+1" post is followed by a consecutive "+2" post by the same user? Surely that is OK?
Normally the moderators would delete that.
For example, if someone were to post
The new MacBook Pb is too heavy. It needs to go on a diet.
And then someone else posts
I concur.
Then it will be deleted by the moderators. It's very short (which is on the moderator radar) and is just wasting everyone's time. If they only happened occasionally then it wouldn't be a problem but there are a lot of them, so it's one rule for everyone, no posts that are just affirmative.
The following example would, on the other hand, be acceptable
I agree that the new MacBook Pb is too heavy to carry, and it should stick to SlimFast for breakfast, lunch and a normal healthy meal in the evenings.
The meaning is the same but it is more verbose and takes longer for the poster to write, thus engaging their brain more than a simple agreement. To phrase it differently if you want to duplicate what someone else has said in
a prior post then you should write it in your own words.
(With appologies to Doctor Q, I'm in total agreement with this policy on moderation, it keeps the forums clean and largely useful rather than a series of pointless posts like this one).
