No, it looks like every few days they pick their showcase list and that list is attached to all their articles that get published for the next few days.
Irrespective of whether they are on the sidebar or anywhere else, too many links to a page from multiple pages on the same domain aren't going to be useful.
To google, it is probably the ratio that matters more. When you have 113K links, they are normally expected to be from a good number of domains. But since you say that 90K links are from one single domain, it might be very difficult to overcome algos like penguin and panda.
and that list is attached to all their articles that get published for the next few days.
Since they might choose to showcase different set of links every few days, does that also mean these links are not permanent on their domain and there is a churn? If yes, they aren't useful either.
But it is not your fault and it is sad that people have to consider disavow tool etc. in scenarios like yours, as Google algos go by a defined set of "natural" rules and they are probably configured to not consider these as natural/good backlinks. Hence their disclaimer on "collateral damages".
