I know using ctrl+c and ctrl+v is annoying on multiple sites but consider some of your fans aren't likely to check certain ones for various reasons. Patrons get an email when developers post updates so posting public versions sends an email to those people and some might just use the patreon link to check if their version is up to date. Figure if they found a platform to get info from they are likely to stick to it especially if they gave money on that specific one. Advertising is annoying but it helps bring in fans, hopefully paying ones, but others help with word of mouth. Other places like gamejolt.com, subscribestar.adult, and twitter.com would help get the word out.
