If you cant beat them join them... sometimes I managed to surf with the tides
Why join them, you know what's going to be the fate of those campaigns/bounties?
Do you mean Pump and Dump group?
Most of the ICOs now are just playing with their bounties and the project as well. OP means the pump and dump of those campaigns that after the distribution of their tokens, they will just dump those tokens easily. Well this can't be easily gone, when ICOs popularity is starting to decrease they'll be gone eventually.
