Classic reason: market conditions are not conducive.
Initially, the irresponsible team delayed the distribution, when they arrived at the promised date they would make another reason and the distribution delay was extended. That continues, one month ... two months ... three months ... then the d*mn team disappears without a trace, without any news, maybe engulfed by the earth.
There is another reason that sometimes does not enter, suddenly the name and the results of our work disappear from the spreadsheet, without explanation, whereas previously there was.
KYC is another reason often used by project teams to delay distribution.
An example is Digitalbits. after waiting for months, they postpone distribution again on the grounds that participants
and previous distribution have been reviewed, only 10% of participants will receive bounty rewards

We must take action against projects that do not pay hunters, we must fight back...
