We’ll resolve this on our end in the coming weeks by disincluding retweets from list widgets. Long-term, we’d like to make this configurable and visually distinctive. For now, you’ll just have to wait for us to resolve it or override the lists javascript to not include include_rts=true when calling the Lists API end point.
There’s a bit of code in there like:
else if (this._isFavsWidget || this._isListWidget) {
this.url = this._base + this.format + ‘?callback=’ + this._cb + showSince() +
’&include_rts=true’ +
’&clientsource=’ + this.source;
}
That just needs one bit removed or commented out:
else if (this._isFavsWidget || this._isListWidget) {
this.url = this._base + this.format + '?callback=' + this._cb + showSince() +
// '&include_rts=true' +
'&clientsource=' + this.source;
}
