hey, AlecaFrame dev here.
~~As far as I know, nothing has changed from their update to the 3rd party policy they made last summer (https://support.warframe.com/hc/en-us/articles/360030014351-Third-Party-Software-and-You) It is definitively not a widespread issue, and no one I have heard of (out of >150K users) has been permanently banned. To me, it seems like their automated system is for some reason being too aggressive with some players, and they just prefer to manually unban people instead of making it less aggressive. Let me try to contact DE directly and see if we can get a more direct stance now that AF has grown quite a bit~~
Update: I asked DE for public clarification, and this is their response: https://i.imgur.com/07aCLNI.png
Even though they won't publicly commit to saying "yes" to any third-party app, they have confirmed in their third-party policy (and again in this email) that Overwolf, which is the "risky part" (gathering the inventory data), is allowed and doesn't break the ToS.
As they also state, any suspensions (which are extremely rare, <10 reports in over 170,000 users) that their automated system performs are not a reflection of the usage of AlecaFrame [source]. These, which again, are extremely uncommon, are probably a result of their automated system flagging Overwolf/the overlay as suspicious. As these suspensions are just a byproduct of a false positive and not a violation of their ToS, they are usually promptly removed by their support team.
During the year and a half that AlecaFrame has been out, I am proud to say that there have been 0 cases of any player getting permanently banned (with no recourse) due to AlecaFrame.
It is my first priority, and also the one for all the people involved in this (Overwolf) to make sure AlecaFrame is, and will always be, fully compliant with their ToS.
Yes, edited the original message with the update
