GA Lost?

When I started posting in thread 'Cleantech: Fact or Fiction?' I had 7 GAs, and now there is only 5! That happened after I mentioned this on this thread, so someone must have searched my past time GAs and voted against them......

Not that it means much, as I have seen GAs given for humorous postings because that has amused someone, but still it is not fair, don't you think?

Actually I noticed this before also as at time I collected 14 GAs, to find only 6 after I returned to CR4 sometime later....

Such practice devalue GAs, and I would say there was a reason for introducing them, as readers of posts could concentrate on persons that have greatest average of GAs compared to number of posts written.......

I propose therefore that positive and negative voting for GAs should be done in relatively narrow time span and then resulting GAs ought to be locked, as some of them are really deserved and hard earned.
