I have a project that's relevant here - netograph.io captures low-level data on website behaviour, then indexes the data in various ways for querying. Right now, it ingests a sizeable fraction of links on social media live. Here's my data for the api.behavioraldata.com domain, which is the first tracker they mention: https://netograph.io/datasets/social/domain/api.behavioralengine.com https://netograph.io/datasets/social/domain/api.behavioralen... It's interesting that Netograph has seen this exclusively on .pl domains, and that it hasn't cropped up again in the last month. You can do similar digging through the dataset for all the other trackers they list.
