I advise against using any bid bots at all as a general rule, but some people are flagrant abusers, spammers, and plagiarists while others just look for an occasional boost to original content. I have far less objection to the latter.

I would like to see more curation efforts, and the various guilds have done a lot, especially since the last fork. I don't personally follow vote trails, up or down, because I prefer to manually curate 100%. I understand why some prefer to follow guilds with good manual curation policies though.
