Hi,

196.52.0.0/14 was recently revoked by AFRINIC.
However, more than 350 prefixes inside of this /14 are currently still announced.
This is all unallocated and should not be routed at all.
Example
https://bgp.he.net/net/196.54.129.0/24#_netinfo

Here is a full list of them https://pastebin.com/raw/MHaW3nPe

Greetings,
