In a bid to fight bounty scammers and spammers on the telegram campaign, there is a great wisdom in the format adopted by julerz12 in his GEOMA bounty campaign (https://bitcointalksearch.org/topic/endedno-kyc-geoma-dao-cares-for-the-future-bounty-pool-wescrow-5223521), you are first told to answer questions on a google format just to test your simple knowledge on Cryptocurrency and then still require you to apply on google form together with Proof-Of-Authentication on the bounty thread.
Some hunters just quickly come to the google application form, deplore several telegrams or even steal some bitcointalk users telegram username who are not participating in telegram campaign, and use it to cheat. This is why we do see over 2k-8k telegram applicants on a single campaign on the spreadsheet which sometimes will give the BM and his team a hard time verifying and sorting out real workers from cheaters and spammers, they may not be able to fully do a perfect job.
This style employed by Julerz in GEOMA bounty campaign is a step in the right direction which I believe has helped to chase off some telegram scammers and spammers off this campaign and thereby reducing applicants to only serious campaigners and at the end will lessen the overall job of the BM. There were days I got discouraged seeing over 8K in some telegram campaigns.
Let me hear your suggestions too. Thanks.
