Previously here [webmasterworld.com] (February 2017).

Saw it again in today's logs and was prompted to take a closer look.

IP every time I've seen it, going back to 2014:
99.229-232 (last time I checked, this was Rogers Cable)

UA, 2014:
HTTP/1.1
TinEye-bot/0.02 (see http://www.tineye.com/crawler.html)
requests, site A: page, sometimes with images (giving page as referer), each visit preceded by robots.txt
requests, site B: non-script piwik dot (only) belonging to sites A and C, each giving a relevant page as referer (I couldn't check Site C logs, but Site A coincides with a page visit)

UA, 2016:
HTTP/1.0 (every time)
TinEye-bot/0.51 (see http://www.tineye.com/crawler.html)
requests: page, preceded by robots.txt

UA, 2017:
HTTP/1.1
TinEye-bot/0.61 (see http://www.tineye.com/crawler.html)
request: image preceded by robots.txt
image request has implausible referer

UA, late 2017-present:
Mozilla/5.0 (compatible; TinEye-bot/1.31; +http://www.tineye.com/crawler.html)
requests: images only, again with highly implausible referer each time

The sample size is obviously not huge, but there was more than one of each.

I don't think I ever realized that they sometimes requested pages; the ones from 2016 were blocked, so out of sight out of mind. I have no reason to think the images over the past year were hotlinked; have they been coopted to partake in referer spam, or is it another attempt to fly under the radar? (Backfiring badly, if so.)

Ever since they launched their Chrome browser extension (see: [webmasterworld.com...] ) and started coming from ISPs, I've seen a significant increase in their bot activity.

I have no reason to think the images over the past year were hotlinked; have they been coopted to partake in referer spam, or is it another attempt to fly under the radar?

My assumption is, each time someone uses the app interface to " find where that image appears online" if it is your image or merely a similar one to yours, one of the stops will likely be your server, independent from any hot-linking issues.
