I posted this to this person but honestly if anyone wants to use it you're welcome to. As long as you're okay with not having any guarantee of funds or uptime.
It is my personal node so I will do my best though. I have redundant storage and backups. That said I wouldn't use it for any large amount of funds. If you want an LNbits account with a LN address I can set that up for you too for a small fee rate.
