Neat URL - Add https://citiretailservices.citibankonline.com to default list?

So there are multiple Citi cards that get offered through retailers. Such examples are: Exxon gas cards, Shell gas cards, Shop Your Way Sears credit cards.
They go under the domain:
https://citiretailservices.citibankonline.com/

So for each of these examples:
Shop your way - https://citiretailservices.citibankonline.com/RSnextgen/svc/launch/index.action?siteId=PLCN_SYW
Exxon Mobile - https://citiretailservices.citibankonline.com/RSnextgen/svc/launch/index.action?siteId=PLOC_EXXONMOBIL
Shel - https://citiretailservices.citibankonline.com/RSnextgen/svc/launch/index.action?siteId=PLOC_SHELL

This is what happens if this domain isn't blacklisted:
https://citiretailservices.citibankonline.com/RSnextgen/svc/launch/index.action?siteId=null&JFP_TOKEN=VXFVO41S#signon

Take note that siteId is not null instead of the corresponding site identifier.

I have no issues just adding this to my blacklist, but I thought it'd be worth mentioning. Thanks
