There's no reason I can think of for why the HTML couldn't include a tab character.
However, if it really is difficult to do, I'd recommend converting tabs to spaces right in the code editor so that the spacing matches when you've copy/pasted a script from a question and are editing it.
Some people like to mass -1 others (ex. out of revenge), which is why (I expect) you can't access all of someone's answers/questions - because of this, I don't want to publish the answer (I expect it can go the other way, too -- a few popular/famous users might get +1s that they wouldn't have had they not been famous). Since you have answered a lot of questions, I'll trust you aren't doing either; I've PMed you on Roblox the answer to your question.
