"I would like to propose that IPs of [NTP] pool-members should not be allowed to host [Tor exit nodes] simultaneously under the same IP."
or put another way, "my employer paid for this whizzy firewall but it complains when we make it talk to a free service run by a volunteer because of other software the volunteer runs. Please educate your volunteers about how they need to go about providing this free service to us."

Pool Member hosting Tor Exit Node with same IP
Hello everyone, I would like to propose that IPs of pool-members should not be allowed to host security-relevant services simultaneously under the same IP. For example 185.248.141.34 is also hosting a Tor Exit Node which triggers automated blocks on firewalls, IPS-devices etc. making the pool difficult to use as this might cause NTP problems. A blacklist API of a service like Abuse IPDB or Criminal IP could be used to check IPs on registration and periodically afterwards. Kind regards

Evading Overlapping Community Detection via Proxy Node Injection
Protecting privacy in social graphs requires preventing sensitive information, such as community affiliations, from being inferred by graph analysis, without substantially altering the graph topology. We address this through the problem of \emph{community membership hiding} (CMH), which seeks edge modifications that cause a target node to exit its original community, regardless of the detection algorithm employed. Prior work has focused on non-overlapping community detection, where trivial stra…
