Your torrent information was collected by a DHT crawler, it's safe to say that this probably isn't associated with Tixati. The parties operating these crawlers are sometimes doing it to scan for CSAM, or in the case of BTDig they do to build a database of DHT torrents that can be searched. IKnowWhatYouDownload.com also crawl the DHT network.
However these Amazon/Linode IP addresses have annoyed me in the past, so I made a script to block them utilising the 'IP Filter' feature that exists within Tixati. Here are some IP address you can block:
Amazon:
https://pastebin.com/yUS6e9Vy (After 24h blocked: 202 In, 167 Out, 7,389 DHT)
Google:
https://pastebin.com/8zWbjzzZ (After 24h blocked: 5 In, 6 Out, 502 DHT)
Linode:
https://pastebin.com/Q9F1nkWm (After 24h blocked: 0 In, 19 Out, 1,070 DHT)
Microsoft Azure:
https://paste.ee/p/0jwCA (After 24h blocked: 118 In, 3 Out, 327 DHT)
As you can see it's probably worth blocking Amazon and Linode IPs since they're the worst offenders when it comes to crawling DHT.
