I just saw BitList in the top banner spot... very cool 
It would be interesting to hear if any services contacted Bitlist owners and requested to be listed there?
Maybe it would be a good idea to add some type of Listing form, similar like kycnot.me have with Request page.
The ad banner on the forum is good, it's a very good extra promotion for the site/service alongside the ongoing signature ad campaign.
And as for the idea of creating a listing form on the site which interested services can utilize as a means of contacting Bitlist for listing, that's a good idea, but I think it's too early yet, I believe there are still alot of features to be added to the site, and as well as alot of marketing to do as well, the sites need to become really popular and drive good traffic to attract services and platforms to want to list their product or service on the site.
So, right now, I believe what is needed more is brand building, getting Bitlist out there through various means available, and this is why I still think we need presences on social medias like X, telegram and other places.
