It's not for pool operators to provide free bandwidth for you. Nor should any pool operator who cares about security for their users be opening their firewalls to their wallet servers - even if there are no known exploits for blockchain sync connections at present, I would consider that an unnecessary increase of the attack surface, and wouldn't expose users at https://bltz.crunchharder.net to an unnecessary risk.

What should happen is seed nodes in the source code, and seed nodes provided by _you_ running at launch, all it takes is a few cheap VPSs.

I mean, good on you for releasing a working wallet that compiles and works fine etc. which is more than a lot of launches, however more nodes should have been provided - it's not the pools responsibility to do that.
