I fully agree with Cynthia here, we use the maintainer STACLAR for example.</div>

I have looked through the database files and there seem to be exactly 26 maintainer objects that are named as an ASN (without any prefixes or suffixes). I think the best solution would be to just block the creation of new objects like this and manually check
through the existing ones to find potentially fraudulent ones.</div>

It is possible to change this, but it'll take some time: extensive research to figure out a path which causes the least disruption to the fewest amount of people. Ideally only a handful of people have to change their "mntner:" primary key.<br>
<br>
I think a mandatory "-MNT" or "MNT-" or "-MAINT" is helpful because the maintainers primary key string does pop up from time to time without any context, and this can lead to confusion. See
<a href="https://seclists.org/nanog/2020/Jan/650" rel="noreferrer" target="_blank">
https://seclists.org/nanog/2020/Jan/650</a> for a fun story about how one person's email error code is another person's BGP autonomous system reference. :-)<br>
<br>
It starts with a volunteer who does some digging in the data to see if a migration path can be constructed or not. A conclusion may be that it is too hard, but we don't know yet. Are you up for it? :)<br>
<br>
Kind regards,<br>
<br>
