So maybe people in the future can read what we did in our time 
If this is the main goal, there are some centralized service which store message/data, such as,

You also can use distributed (such as IPFS and BitTorrent protocol) or decentralized alternative which already mentioned.
“web3” stuff can use IPFS, which I linked to in my prior post, among other options for storing data that are too big or otherwise unsuitable on the blockchain.
I'm a member of a discord group that stores archives of old stuff (we're talking magazines, siterips, video documentaries etc) on an open directory, who currently possess several hundred TB of historic data, and they know a guy who tried to host all that stuff on IPFS.
Long story short, it split all the hosted data into many chunks which caused extreme throttling on his HDDs and he also got a bunch of unnecessary traffic from the rest of the IPFS network who are trying to go to other locations. He ended up decommissioning it.
Do you know whether it' hardware limitation or limitation of IPFS software which isn't designed to host hundred TB data? If it's hardware limitation, using SSD would solve the problem, just like how you run ETH full node.
