(With the exception of the meta sites, which of-course have the support tag, as used by this support metaquestion.)

@Jenny D: I thought that support queries were off-topic on Stack Exchange. If a question is not a support query then it should be possible to rephrase it generically. In other words, if it's impossible to phrase a question generically then it should be off-topic on wiki-style Q&A sites such as those of the Stack Exchange network.

“If you think a question is good enough to deserve an answer and you take the time to provide one, why don't you vote it up?” – Because often good underlying questions are asked with barely any effort. On other wiki-style sites (those without a rep award system) I would simply edit the question to make it clearer. But here on Stack Exchange, that would mean that the user who made no effort would get lots of rep points for the resultant upvotes and I'd get none.

That's because you've written it like a support query rather than a Q&A-style question. If it's impossible for you to troubleshoot without your specific domain then how is it possible for anyone else to use it to troubleshoot their similar problem? Questions are meant to be well-researched, useful, and clear – I don't think that (currently) your question is either of those. If the question is appropriate for the Q&A format then it really should be possible to rephrase it to be more generic.

Unfortunately, trying to evade crawlers by using imaged text without an alt-text description is also bad for accessibility. I encourage you to make an effort to write your questions without resorting to such a bad practice. Try to rephrase the question without the specific domain name. If you really must include a domain name then try to use example.<TLD>-style domain names instead of one that you're actually trying to keep private.
