Ban SamLau95/nbinteract-image

[betatim]

This bans SamLau95/nbinteract-image as they are using up their 100 slots (and more) if we let them.

This is the referrer causing the build requests: https://www.nbinteract.com/examples/examples_empirical_distributions.html

https://grafana.mybinder.org/render/d-solo/fZWsQmnmz/pod-activity?refresh=1m&orgId=1&panelId=1&from=1527811368023&to=1527897768023&width=1000&height=500&tz=UTC-07%3A00

It isn't causing any trouble yet but rather ban it now instead of have some problems over the weekend when everyone is away.

@betatim perhaps this is another user who has left open the eventloop? That's what it was before...

[betatim]

The weird thing is that there were no changes to the nbinteract code. So maybe a broken browser?

[choldgraf]

well every now and then if a user of nbinteract leaves open their browser and the eventloop stays open, it'll just keep re-sending signals to binder to build, and this continues until the person closes their window :-/

[betatim]

The behaviour you describe sounds like a bug in nbinteract. Not sure I understand why nbinteract should ever leave the event source open unless there is a bug in nbinteract or the browser wrt closing the event source.

[SamLau95]

Heya @betatim @choldgraf , I've attempted to replicate the thebelab implementation of EventSource handling in SamLau95/nbinteract#82. Can we unban SamLau95/nbinteract-image to see whether we get lower load?

[choldgraf]

@SamLau95 sounds good to me...I'll do this now
