Would it help if I add the following header to every large batch of queries?

This is already more detailed than what I had in mind. Having a way to tell apart bots and tools from "organic" queries would already be great. We are mainly looking for something that will help us to understand sudden peaks of activity. For this, it might be enough to have a short signature (a URL could be given, but a tool name with a version would also be fine). This is somewhat like the "user agent" field in HTTP.
But you are right that some formatting convention may help further here. How about this:
#TOOL:<any user agent information that you like to share>
Then one could look for comments of this form without knowing all the tools upfront. Of course, this is just a hint in any case, since one could always use the same comment in any manually written query.
Best regards,
Markus

Dear SPARQL users,
We are starting a research project to investigate the use of the
Wikidata SPARQL Query Service, with the goal to gain insights that
may help to improve Wikidata and the query service [1]. Currently,
we are still waiting for all data to become available. Meanwhile, we
would like to ask for your input.
Preliminary analyses show that the use of the SPARQL query service
varies greatly over time, presumably because power users and
software tools are running large numbers of queries. For a
meaningful analysis, we would like to understand such high-impact
biases in the data. We therefore need your help:
(1) Are you a SPARQL power user who sometimes runs large numbers of
queries (over 10,000)? If so, please let us know how your queries
might typically look so we can identify them in the logs.
(2) Are you the developer of a tool that launches SPARQL queries? If
so, then please let us know if there is any way to identify your
queries.
If (1) or (2) applies to you, then it would be good if you could
include an identifying comment into your SPARQL queries in the
future, to make it easier to recognise them. In return, this would
enable us to provide you with statistics on the usage of your tool [2].
Further feedback is welcome.
Cheers,
Markus
