That is of course assuming you want the skimmers to spot you.

Thanks to an off-reflector message from KU5B (which I have somehow
misplaced), I can confirm what I thought had happened. He did not use
the key words "TEST" or "CQ" in his CQ message, so CW Skimmer did not
recognize him to be calling CQ.
There are some other key words that would have worked the same way, but
Alex has asked me not to talk about CW Skimmer details. However, I
don't believe "NA" is on the list, and it should be.
As it is currently configured, the RBN Aggregator software, which each
RBN station runs to send information to the server, does not forward
non-CQ spots to the "mother ship". This is because to do so would badly
overload the server. That precludes our doing any post-processing, to
identify runners that Skimmer has missed.
In coming months, we may be able to change this, but for ARRL DX, I
suggest putting TEST in your CQ messages periodically to make sure
