If a user is suspended on some site, they cannot interact with the site using their account.
I have read in several places that creating another account to bypass suspension is wrong. (In general, if a user has multiple accounts they should not be used to do something which can be done from single account. This would be an example of violating this rule.)
Still, if they access the site while logged of, they still can:
- ask question (with exception of some sites where only registered users can post question);
- post answers;
- make suggested edits.
Using cookie-based account bring some problems - since user might eventually lose access the account and they no longer can comment under they questions/answers. This is more problematic for questions, but perhaps not such a big problem for answers. Suggested edits seem the least problematic from this viewpoint - other than approving/rejecting edit you seldom need to interact with the user who made the suggestion.
I can imagine a user who invested a lot of time in some site, so they care about it and want to help the site - but for some time they are not allowed to. Making some anonymous edits would be at least some way for them to help while they are on the naughty step.
Question: Would contributing using unregistered account during the period of suspension still be considered a violation? Are at least suggested edits from such users allowed?
