Is it legit to create private giveaways with only one participant?

Probably fake giveaway + fake profile.

no. i created a private giveaway for two of my mates a year ago and one left the giveaway before it ends.
...lots of trouble.

just don't do it.

it's not against rules. but it's not considered giveaway.
less than 5 participants and
you won't get CV.

And what's point of that except of trying to exploit CV? If you want to give game to this person just give it directly through steam without help of SG

Legit but pointless as there is no CV gain :)

Only if you want SG will choose your best friend instead of you ;)

My last private giveaway was for 2 groups with +70 people in total, and only 3 participants... :-/ I won't do a private giveaway in a long time.

is it legit? yes.. you can do that if you want..... dont know why you would want to, you might as well just GIVE it to the person, unless the real present you're giving to them is the ability to witness the cat freaking out...

but if you wanted to cheat CV, which is a shitty thing to do, you need a minimum of 5 entries at least.

It is legit, but you won't get any CV, so you can just give it to him directly.

you can do it, but you will not recieve any cv.

i did one with only one entry because of a puzzle only one could solve in time for the first ga.
(i had a second ga with longer timer that had 2 entries for the same puzzle)

It's cool but, as everyone else said- no CV.
And as for why make it- well I got a gibs created just for me once and it was totally awesome because it was a part of a joke and the guy who created it is just the coolest ever xD

He still not gonna win it.

its ok, but it anyway won't give you any CV

Why 5 entry ? why not 6 or 7 or 10 ?
