I am thinking that I may leave @Decoded negative feedback. Ideas?
I wouldn't tag him for this, it doesn't fit the description:
Negative - You think that trading with this person is high-risk.
Personally, I couldn't care less if I'm blacklisted from spamming bounty campaigns.
I also know it's a terrible amount of work to manually go through thousands of lines in a spreadsheet, and remove the many imposters. It gets worse if they can just use the same wrong username again. That just means the campaign has fundamental flaws.
I've reported, I've got this answer:
Bitcointalk accounts are used for communication and banning in subsequent campaigns
This doesn't make sense. It's not allowed to send bulk messages based on entries that anyone can make, I haven't received any communication based on the fake entries, and blacklisting is useless as long as they can use random accounts.
A very easy fix would be if the bounty campaign doesn't ask for Bitcointalk usernames at all.
And if they insist on using Bitcointalk usernames, this offer is still valid:
Can I offer my scraping services?
It's very easy to make this abuse impossible.
