Recently it's been happening that almost every bounty keeps on extending with some even going into 6 months - 1year. It's very bad for a bounty worker because some projects even end up being scam. Anyways I think it is somehow good as well since some people have been cheating in bounties a lot.
If bounties keep on extending, cheaters will keep on working for wrong bounties for a long time and new hunters will also have the chance to join. This is because some bounties have so many participants and so we need to spread ourselves so that we can all equally earn. Also, the recent forum rules will help in taking care of so many cheaters or multiple people joining the same bounty.
Nevertheless i still stand by the point that bounty extensions are very bad.
Bounty extension isnt ideal for everyone especially in siganture campaigns which the more you stay the less you will get because only those high ranks will gain more in a longer campaign.This can only be resolved if and only if these campaign managers are going to limit the number of participants so the hunters are going to get what they have worked for.
