I don't expect that payback will stop anytime soon - but we might be sharing the same budget between more people.
I was thinking that!
The more giffgaffers the less payback to go round, at some point in the future the flood of new giffgaffers will put paid to large payback amounts as so many will be trying to earn..
I have noticed on some threads there are lots of the same answers posted by different giffgaffers all trying to get a Kudos mark for payback, this is quite annoying actually as I don't want to read 12 posts all giving the same solution to a thread with only 13 total posts in it!
Think it needs to be addressed if the Giffgaff forums want to progress and I think need moderating more closely for this.
I moderate on another forum and we would certainly clean a lot of the threads up for duplicate posts
