Some of the bounties have a limit of participants. Because of this some people reach late and are not allowed to participate then for those users they have to search other bounties but some times there are more number of users the tokens received are very less but they are valued very high.

I do not see this as a big problem, the budget of most of the bounty campaigns is enough for all participants. So do not worry.

I choose a project to participate in it by the number of participants. for me, this is essential, because if other people trust the project, then I should pay attention to it

in my opinion do not use fraudulent ways to get a lot of benefits for yourself. many campaigns that can be followed if you are great try to join for all campaigns such as signature, translator, bounty blog and sosmed and others. I think this way would be better than using a cheat way with multiple accounts

I have a suspicion that some bounty platforms use a farm bot, an example: at night I receive the notice, on bountyhive the new company, and in the morning there are no empty seats for participants any more. How to explain it? Huh

Bounty is meanly used for promotions for an ICO’s. There are many bounties to grab, the opportunity is huge

This is normal. many participants in projects with a large reward.
In a bounty where the reward of a small people simply will not go after a certain number of participants. Otherwise, the work loses its sense.

I think it would be nice to have some restrictions . But beginners can and many but few people know how and where to find a good project . As well as a lot of projects and there is no sense . (((

Already lots of better rules and regulations are made  by the team of this forum and by the supports of this forum who are doing some better work to report worst posts .
Here if you will try to see the rules and regulations of the participants to join the campaign and the rules made by the forum to run the bounty campaign than that will be really much hard to follow all rules , so here everything is already made to be better in future but a big problem is that here in this forum lots of crowd and traffic by the new new users in populating and that is unstoppable for us because this forum is free to use and every new member can give better support in this field (but most of them only spamming by making lots of stupid posts to make earnings ) .
Well here new rule of the merit system will surely make the forum to work with more competition with better quality things and than people will be limited here to get rewards like things , but here we can say about the airdrop because that is totally regualted by the ICO team .
