UPDATE The OP has reached 40 views with nem. con. and tag hack is now no longer in use, tag hacked has a Usage guide, presently:
For questions about the consequences of unauthorised access to an account or for recovery procedures / damage limitation where such access has been obtained. Use a tag like [security] or [privacy], as appropriate, for questions about how to prevent unauthorised access.
and there are no Qs (at present) applying both tag security and tag hacked.
“hack” in the sense of a workaround is a meta concept and is not appropriate as a tag. The sole Q with such use has other tags and does not require hack which should be removed there and never used again.
“hacked” is a common term for accounts that have been compromised and is a concise and meaningful description of either the owner's complete loss of access to an account or the sharing of access to an account between its true owner and one or more others not authorised by the true owner.
“hacked” in the sense of purloined account is approximately the opposite of tag security and is as valid a tag as that. “hacked” is a consequence of security that was not of a high enough standard. Being close to antonyms, the two should not normally be applied to the same Q – either the emphasis will be how to prevent being hacked (use tag security) or how to recover from a breach of security (use tag hacked).
