I'm having trouble understanding the SHA1(SALTPLAIN) in disqus dump.

I would normally think the salt, in hex there, would always be divisible by 2 when in hex chars, not an odd number (like five chars). Although I suppose anything is possible.

The first few hashes look really hairy, lots of leading zeros. Reminds me of finding a PoW hash in Bitcoin mining

So can someone help with the disqus format, which looks like this?

... lots of others, all the same. Maybe the salt has been accidentally cut off? Maybe it's encoding the salt in hex improperly? Or am I misinterpreting the hex and it's something else that looks exactly like a hex string?

Is SHA1(SALTPLAIN) the same as hashcat mode 120, i.e. sha1($salt.$pass)? Maybe there's an iteration in there that I'm missing?

Thanks for any help.
