| When it is usually not appropriate to request CheckUser, although exceptions may exist |
| Situation |
Solution |
| Obvious, disruptive sock puppet |
Block. No checkuser is necessary. |
| Disruptive "throwaway" account used only for a few edits |
Block. No checkuser is necessary. |
| Checkuser on yourself to "prove your innocence" |
Such requests are not accepted. Please do not ask. |
| Question about a possible sock puppet related to an open arbitration case |
Request checkuser on the arbitration case pages. |
| Vote fraud on ongoing vote |
In most cases, wait until vote closes before listing. For exceptional high profile debates where possible disruption may need quick attention, note the concern at Wikipedia:Administrators' noticeboard/Incidents to draw it to administrator information. |
| Vote fraud where the possible sockpuppet votes do not affect the outcome of the vote |
List on Wikipedia:Administrators' noticeboard/Incidents, or request examination without CheckUser. |
| Suspected "good hand bad hand" use to avoid scrutiny |
Request sock investigation only initially, in most cases. Depends upon severity. |
| Suspected administrator sockpuppetry or multiple account abuse |
In general this should be reported to the Arbitration Committee and not posted on the wiki. Reason: - if an administrator were indeed abusing their access then this is an Arbitration Committee concern. The user's admin flag may need to be summarily withdrawn without notice in serious cases, if proven. |
| Other disruption of articles |
List on Wikipedia:Administrators' noticeboard/Incidents, or list here with a question whether checkuser should be requested. |
| Open proxy where you already know the IP address |
List on Wikipedia:WikiProject on open proxies. |
| You want access to the checkuser tool yourself |
This is not the page to request access. Please see Wikipedia:CheckUser for more. |
