A request to ignore all users wearing their signature is also an alternative if they don't take this post seriously.
A request to whom?
To everyone not part of their campaign I guess. I noticed that the accepted participants have prior tags and I doubt they will leave. I'm pretty sure 1xbit wouldn't remove them because they were tagged from joining their campaign. So I thought why not just ignore all their promoters and starve 1xbit of our attention?
Personally, my ignore list probably doubled when I visited their signature thread yesterday.
