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.
Its happening since few months ago, they keep on extending the bounty program, the longer the time span, the shorter the value, and i remember one of the project that extended for few months, and at the end, the value of my token received was above 1usd. This is an absolute abuse to the honestly, and i dont like this. I am more selective when it comes to project promotion.
