Yeah, this kind of sucks.
They should not have Invites, only members. Is enough they premined 36 Million coins.
This is greed.
I do agree that this account should not receive invitation rewards or it should be stated in WP what is a purpose of those coins and to who they belong. I think that those funds should, at least, be transferred to zero-wallet.
Now regarding invitations:
Its starting phase of project and lack of invitations was very visible during epochs 35-43 (people were paying for them) - This account invitations was really helpful than. Now it's not and as we can see person responsible for this account is sending less and less invitations. I think that current epoch will need a lot of help from this account to help all killed accounts get back to mining. This account is a security buffer for cases of excessive hype (epoch 35-43) or the current crisis.
Note: The developers decided to hide the reward page for this account after members have been calling them out for keeping the invitation rewards.
You can still track them here (just change 45 in URL to any epoch you would like to check):
