Hey @neoxian, you can add direct witness link on your post - maybe just below your signature (footer). That way some less tech savvy people will able to click it and join themselves as your witness. I hope the shame-list people can take a lesson from it.

Even though your suggestion is good I guess it won't changes much. Those people are in my opinion mainly after upvotes. They most likely saw @neoxian upvoting a true fans post and though they will get it to. Everybody writing now they did not know how to vote for witnesses are straight up lying. There is no way they can start a computer and log in to steemit but aren't able to find out how to vote for witness (since it is basically 2 clicks). And if they didn't really knew how to do it in advance it's about a 10 second search to one of the many "how to vote for witness guides" out there. If they had any intention or compassion to do it, they would have done it.
