I'm inclined to just let you specify a regexp of patterns to ignore when matched out-of-context. For example, Q1..Q4 are commonly used to mean "Quarter 1" through "Quarter 4". I think we implicitly ignore these right now, but it would be better to make this explicit.

You could then ignore all W... patterns.

Specifying regexps would be a nice option.

One could then invent a syntax to explicitely activate the ignored link again if necessary, e.g. something like ![W..] or !{W..} for inline links, respectively

In the meantime, i really would like to deactivate this in our install. Would patching this here be easy? If so, where do i look?

Make PhabricatorApplicationDashboard->getRemarkupRules() return an empty array.

That was easy!
Thanks

Path forward here should be something like this:

• Add an option like remarkup.ignored-object-names, which has a regular expression.
• Default value should be something like /^(Q|V)\d$/ I guess, to blacklist Q1 through Q9 and V1 through V9. I think these are the only things that sometimes conflict with normal, non-specialized text.
• In PhabricatorObjectRemarkupRule->markupObject(), test $params['ref'] against this blacklist, and return the original text if the ref matches.
• Remove the hard-coded blacklisting of Q1..Q4 in PonderRemarkupRule.
• Maybe mention this in the Remarkup documentation.
