[Updated] Evil network: Donstroy Ltd AS29557 (194.8.250.0/23)

UPDATE:  this IP range is now used by a completely different organisation, and malicious activity no longer exists and the block is safe to use. However, the post will remain up for research purposes.

Another network worth blocking, Donstroy Ltd appears to be a Latvia entity hosting in Moldova, closely affiliate with Sagade Ltd who are one of the most scummy networks around at the moment.

The WHOIS details show a tell-tale link to Sagade in the email address:
