More on topic I have used the arrows mostly as a sign of agreement or respect.
Or as for me ,If anybody adressed allready what I was going to say anyway or even better I just give him a plus 1 for that. But I do give a minus for bad language or an insult.
If you have a diffrent opinion? it’s ok. We agree to disagree, but if you start to insult somebody as a protest I do minus that.
Would have? No reason for this past tense phrasing. Any person who is abnormally fixated on nothing but gearing up the number of posts by hook or crook has many sock puppet accounts.
They will be the ones who post like 25 times a day everyday in one sentence posts.
