Is it just me or is it odd prism responded to their own comment just to complain about their downvotes several days after the initial conversation? That seems like attention seeking behavior. I feel bad the mods have to deal with that. Maybe prism should work that energy towards something more productive than arguing with strangers online.
As for the over bumping, i agree its a bit of an issue as finding avatars without the search bar is exponentially harder when you have to sort through bump comments to see a DL link (Just an example as not everyone updates their posts when found) but being a noob myself i also understand a lack of knowledge from most new and frequent users on the silent rules of forums and how to use forums properly in general as it differs.
You kinda haveta jump in and figure it out as you go it seems. Not many people use forums nowadays either and each layout is different so it can be confusing switching between sites. Took me a while to figure this site out.
I think having a limit on bump comments (like limit it via a filter) or make a bump button for posts to be boosted instead would work. I dont know much about sites and coding so im not sure if itd be easier for them to integrate a filter or a button instead.
Just my Two Cents on it.
