The system could work with a revamp. Also, some services are offering free certificates if you push a verified apple dev account to them. Which in turn, will be shared to others and the fees being paid by the said service. They just need IDs verified accounts.
There is also another way to create such verified accounts, but am not gonna put this out here in public.
But maybe just offering the way of getting free certs by giving out your verified dev account and limiting the shared slots to the minimal could help. If one shares, it can go up to 20 peoples having certs, If enough people are willing to start going this path just providing an id and having a free cert on their own dev enrollment, not only you can spread the certs to most of the community while spreading out but also make a secure move for which one taken down wont take down the service and can be pushed into remaining non-revoked ones temporarily, until some more comes in giving new accounts.
This is not ideal but it works. There, if you ever want to offer such services, you'd need to be very careful and spread tons of different certs cause iosgods is just the first target. Which also means that if you rely on third parties, they may fall down as well and as quickly cause in the end, there will always be revokes there out due to the popularity of iosgods, funding certs by your own ways or through third parties, doesnt change, it'll get revoked. The only way you can make it decent enough to be viable is to either make your own third party and do not advertise it much there or just having the community participating on a large enough scale to out run the revokes. If you end up having enough participants agreeing to share such accounts, they'll have a bad time to stop all certs at some point. And if they do hit some, you can quickly replace by spreading through those that are still up as I said.
That is the cost of being the top 1 ios modding website. Sadly.
