The following game caused a bit of head-scratching here at jeromegambit.blogspot.com...
Doctoroldhead - chesstux
standard, FICS, 2012
1.e4 e5 2.Bc4 Nc6 3.Nf3 Nd4
The Blackburne Shilling Gambit.
4.Bxf7+
The Blackburne Shilling Jerome Gambit.
4...Kxf7 5.Nxe5+ Ke8 6.c3 Qg5
Now, White forfeited by disconnection.
It is hard to know if White simply lost his connection to FICS at this point. If he did, maybe he was not able to log back in and continue the game. Or, maybe his opponent had set his "noescape" variable so that any disconnection would be treated as a forfeit.
It is also possible that White saw Black's last move - thematic to the Blackburne Shilling Gambit (and its relations) - and figured his Jerome Gambit strategy had failed. So, why play on?
I checked The Database for games with the final position. There were 80 of them, including efforts (with White) by well-known Jerome Gambit Gemeinde members GOH, GmCooper, Darrenshome, DragonTail, drumme, sTpny and jfhumphrey. White scored 54%.
In those 80 games, White's average rating was about 47 points higher than Black's average rating, consistent with White's edge in scoring. Also, Houdini 2, at 20 ply depth, rated White's position to be about 2/3 of a pawn better - again, consistent with the scoring of the games in The Database.
Conclusion: no need for White to despair.
Of course, he needs to find the right idea, which is to capture the Black Knight with 7.cxd4, and after 7...Qxg2, find 8.Qf3. Black then has nothing better (and a lot, worse) than exchanging Queens with 8...Qxf3 9.Nxf3.

White has an edge, thanks to his extra pawn. That is certainly nothing to give up on, unless things beyond the chessboard were more pressing.
There is a fine line in chess between "chaos" and "complications" – and the Jerome Gambit and its relations, in this case, the Blackburne Shilling Jerome Gambit – tend to trample all over that line, especially in blitz chess.

1.e4 e5 2.Bc4 Nc6 3.Nf3 Nd4
The Blackburne Shilling Gambit.
4.Bxf7+
The Blackburne Shilling Jerome Gambit.
4...Ke7 5.Nxe5
Needlessly complicating the position – but what is chess without complications?
5...d6
An earlier battle between the two players continued 5...Nf6 6.c3 d6 7.cxd4 dxe5 8.Qb3 Nxe4 9.0-0 Qxd4 10.Qf3 Nxd2 11.Bxd2 Bg4 12.Bg5+ Kd7 13.Qxb7 Rc8 14.Qb5+ c6 15.Qb7+ Rc7 16.Qb8 Rc8 17.Qb3 Bc5 18.Be3 Qd6 19.f3 Bxe3+ 20.Kh1 Be6 21.Bxe6+ Qxe6 22.Rd1+ Ke7 23.Qxe3 Black resigned, crokit - sahistonline, FICS, 2011.
6.Qh5
Letting slip the thread of the game. Earlier in the year Black faced the stronger 6.Bxg8 (good at move 5 as well): 6...Rxg8 7.c3 (7.Nd3 Ke8 8.Qh5+ g6 9.Qd5 Nxc2+ 10.Kf1 Rg7 11.Nf4 Re7 12.d3 Nxa1 13.Qc4 a6 14.b3 Bd7 15.Bb2 Nxb3 16.Qxb3 Bc6 17.Bf6 Qd7 18.Bxe7 Qxe7 19.Ne6 Kd7 20.Nf4 Bh6 21.g3 g5 22.Nd5 Qe6 23.Kg2 Rf8 24.Nd2 Qf7 25.Rf1 Bb5 26.a4 Bc6 27.Qc4 g4 28.Qc1 Bxd5 29.exd5 Qxd5+ 30.Kg1 Qxd3 31.Rd1 Qd4 White resigned, Doctoroldhead - sahistonline, FICS, 2011) 7...dxe5 8.d3 Ne6 9.Qh5 h6 10.0-0 g6 11.Qe2 Ke8 12.Be3 Qd6 13.Nd2 b6 14.Nc4 Qd8 15.Nxe5 Bd6 16.Nc4 Be7 17.d4 Bg5 18.f4 Bh4 19.b4 Bb7 20.d5 Ng7 21.Ne5 Nh5 22.Nf3 Be7 23.Ne5 Bf6 24.Nxg6 Ng3 25.hxg3 Bxc3 26.Rac1 Bxb4 27.Qh5 Qd7 28.Ne5+ Black forfeited on time, Darthnik - sahistonline, FICS, 2011.
6...Nxc2+ 7.Ke2
Probably best was 7.Kd1, as after 7...Nf6 8.Ng6+ hxg6 9.Qxh8 Nxh8 Black does not have as great an advantage as after the text.
7...Nf6 8.Ng6+ Kxf7 9.Nxh8+ Ke7
Snatching defeat out of the jaws of victory. (...Kg8 looked safe enough)
10.Qf7 checkmate
