I was at Patreon's until recently. Why vote if your option always gets fewer votes.
Most people are happy with the changes . I can't understand it.This suggests a conspiracy theory (this is sarcasm, perhaps).
I was about to write a smartass remark about how democracy is inconvenient and all that. Decided against it... mostly.
And started to write the answer before your edit.
The main thing that comes to mind would be to give the dev an idea how popular various suggestions are. So, if your favorite of 'have her wear white lingerie' came second to 'have her wear only black fishnets'? The dev might keep in mind that place two was popular too and will include a scene with that in the future.
Should your vote have been something like 'have a lavender elephant-man watch them going at it while sodomizing a cookie monster plushie with a carot' and your vote was the single one for that, well, it might be that your preferences are just too specific and personal, and you have to accept that your wishes are too specific to reasonably expect haveing them fullfilled ingame, even if you support the creator on patreon.
