Would it be a difficult task to enforce a rule that users advertising for banned advertisers are given a few days to remove their signature before being suspended/banned?
Would it be difficult to enforce?
From a technical standpoint, no. It would be very easy.
From a fairness standpoint, yes. There could be some people who are advertising a company outside of the signature campaign, for example because they have an ownership stake in the company, or work for the company in a role that benefits when the company has increased sales/volume.
Even if this rule were to be enforced, campaigns could be managed entirely outside of the forum, which would make it difficult to rule out someone using a bunch of accounts to wear a particular signature, and post a bunch of garbage, making it look like the campaign has a lot of people enrolled making lots of shit posts, when in reality, these people have nothing to do with the campaign.
I don't think theymos wants to be involved in giving licenses to get to perform a job.
I meant more along the lines of a community-enforcement; similar to the direction DT is taking.
That is still a de-facto license. I also have a feeling changes will eventually be made to the DT system moving it in the opposite direction from where it has recently gone.
