New restriction on airdrops / proof of authentication posts. Is it real?Reporting Proof Of Authentication postsMost of them used to bump bounty threads. Bounty thread will be hurried in seconds by other bounty threads because bounty hunters spam their PoAs fastly & continuously.
Only very good managers don't ask participants do this.
Users should not post PoA posts if bounties managers don't ask for. In case managers don't require, users who make such annoying posts might be banned.
Anyone posting info from their bounty application (usernames, addresses, etc.) or anything alongside the lines of "joined X", "looking forward to getting X", "thanks for the opportunity", "filled out form", "signed up for X", "applied", "following / liked / retweeted X" when such data is not required by the bounty / airdrop / giveaway / whatever (e.g. the bounty takes entries on a different website) or the requirement is against the forum's rules (e.g. when a giveaway requires users to post entries for low effort tasks) risk having their account banned. These are extremely low quality posts that generate massive amounts of spam, drowning out any legitimate discussion these threads may posses.
I'm not a fan of the proof of authentication posts, and believe there's other ways to automatically do this. Especially, with systems like Discord, and Telegram where they can setup automatic bots to determine whether a proof of authentication is formatted correctly, and acceptable. These could go in a dedicated channel which wouldn't be spammed to the public.
Although, I'm not a fan of allowing this sort of content on the forum it is allowed, unless they're offering an incentive to post them.
There is a page to check patrol, without bounty reports.
