This has absolutely nothing to do with politics and proposing it has is ridiculous. Any decent spam filter seeing 5000+ almost identical emails from one sender to recipients on one domain would be triggered, causing a blacklisting.
As to why the IT department has chosen not to remove Byteball.org from the servers blacklist, I would have to refer you to the Student Council (FCEUSB) who together with the dean's secretary met with representatives of the IT department. They will be able to explain the reason for their request of having usb.ve domain removed from the email attestation bot's white list of domains eligible for rewards.
As already stated, Byteball has absolutely no intentions of causing any harm or problems to neither individuals or systems.
This is nothing but teething troubles for Byteball. If this is sorted out and Byteball gains a committed following among the university students, it would definitely provide a boost for adoption nand Byteball in the long run. The administration may be bureaucratic and slow to act, but I think eventually they will see reason and remove Byteball.org from the blacklist.
