You will have to remember that these are automated mails from the reporter.
If I write them back it goes into their bit bucket, because they do not
really care enough to bother replying. I am betting they are sending out
thousands mails each day and they can not handle manually replying to all
of that. In the same way we receive a large amount of automated mail so we
have to be able to handle it automatically. Send me something sane and I
will make a script that forwards it. Send me something unusable and I wont
- but I will not do manual handling of your automated mail.

All I am trying to do here is tell people that send abuse mails not to
combine multiple abuse complaints in one mail, because that makes it harder
for everybody and makes it more likely that your mail will be dropped as
too much work. Double so if your abuse mails is from an automated system,
because I will try to match your automated system with my own. However it
is much harder to make a system that can edit your complaint and duplicate
it to several recipients, than it is to run a simple filter that just
forwards the mail as is.

As to PSN they will usually send multiple mails if the abuse is ongoing. At
some point they will send a mail with just one IP and that one gets
forwarded. So we are dropping some of the mails, but the users eventually
get notified anyway. It is not ideal but it works.
