if they are obviously bot or dedicated marketing accounts, then no I dont think they should be here.

I would like the rules to make clear what is acceptable.

self promotion of a FOSS project is acceptable in my opinion, as long as it is clearly titled as self promotion and isn’t done in a spamming way (such as carpet bombing multiple communities with bot posts). I’d also say that donation-seeking in those posts should be kept to the creators own web pages, not in the posts themselves too.

there is a pretty easy line to draw for what is blatant advertising and what is genuine discussion of a paid service. that’s not that hard to moderate, especially when accounts are new, and carpet bombing the same posts to multiple communities, that is clearly spam.
