I've had three occasions now when a BBO robot repeatedly bid its weak 7-card suit after I showed a powerful one- or two-suited hand. In the above diagram, as I showed a slam-level major two-suiter, the robot proceeded to bid 3♣, 5♣, 6♣, and finally 7♣ on a 7-card suit headed by the J987 with just two other Jacks in the hand. Highly uncooperative, particularly considering doubleton Jack support for my first bid suit.

 

I think I should have jumped to 6♥ rather than bidding 5♠ in the auction, but there is no way the robot should have called 6♣ over the 5♠ bid or 7♣ over my 6♥ correction.

from other threads if you had opened two clubs and rebid 2nt it probably would have passed

The problem on this hand is GIB's description of your 3♠ bid.

GIB thinks that since West's bid showed spades, your spade bid must be a cue bid showing support for partner's clubs, and absurd strength. So, GIB thinks that after you "agreed to clubs", he tried to sign off in 5♣, but you kept bidding.
