Socialrankio
Socialrankio is a generic scraper with no publicly identified operator. Intent varies case-by-case, some scrapers are legitimate research, some power useful aggregators, some are abusive.
Look at the request pattern before deciding what to do. A polite scraper crawls slowly, respects robots.txt, and identifies itself. An abusive one ignores all three.
If you are not sure, the safest move is to rate-limit rather than block outright. That keeps the legitimate use cases working while neutralizing the abusive ones.

For higher confidence, also verify the source IP against the operator's published ranges. UA strings can be spoofed; IP ownership is harder to fake.
