If the Government is creating a list of no-no words (which in itself is violative of the constitution) it should be required to publish them as "Secret Laws" are defacto unconstitutional,

If the government or some agency published all the indicators of fraud that it used to check that people were filing their taxes legitimately (and catch crooks), how would you ever conduct anti-fraud operations? Every criminal would have the manual on how to circumvent the detection mechanisms and move to techniques that the IRS doesn't know how to detect.
Should the government equally publish its root passwords because that's within your right to be able to know how the government operates also? That would be ridiculous.
If it were just paypal they absolutely wouldn't care about the subject so much as to match random characters in descriptions, wouldn't give people zero recourse, etc.
