Most other forums either outright ban advertising, require that the advertised site links back to them, or have their advertisements screened and approved by the site owner/staff.
Talking about another site has never been banned on any other RP site I've been on. Sure, ads and banners might be, but general chat about it isn't, as far as I've been aware; why does what they do matter, anyway? I can name 2 places already which don't have this rule (I'm currently still on one of them), and the admin of one of them even explicitly recommends checking out others publicly, with BMR being one of them.
And you don't need to behave the same as them, BMR is not them, and they are not BMR.
Guess what also walls people into their garden and enforces talk only of itself and disallows talk of anything else? Cults.
Humanity did not get this far by this level of bickering and hiding stuff; even the reason this website exists right now is thanks to the technology and knowledge of that technology shared to allow it to run, and the sharing of literature and similar throughout centuries, bringing the hobby to light.
I come from a very open field of work and lifestyle, which helps as many people as possible, is as transparent as possible, and shares as much as possible. Who else shares their
entire request thread formatting like I do, under a proper, legally-enforceable open-source license, mainly to protect
members who decide to use it against claims of plagiarism, rather than protect myself?
I don't see the need to say "they started it!". Why don't you "finish it", then? It's not difficult to just be yourself and your own thing, instead of following what everyone else does.
