To be fair to the other bidder in topic and anyone else thinking of bidding, after telling the PM bidder that any further bids needed to be in topic, they replied saying they were under the impression that I'd be selling to them for £80 if there were no manual penalties, which there weren't. That they must have misunderstood me, and if they knew their research would be used against them, they wouldn't have wasted their time on it.
I'm not sure why they thought I was selling only to them, and it was their choice to use their time to check out the domain before deciding if their offer still stood. As with all my for sale topics, I'm open to PM offers, but that doesn't mean if you make an offer it's yours for that price, I'm not aware of anyone who sells to the first offer they receive shortly after posting a domain. As with all my sales posts, if an offer is made via PM, the sales topic is updated to include any offers and to set an end time.
They also said that even though the domain doesn't have any manual penalties listed in Google, they're pretty sure that it has a penalty that is stopping it from ranking well on Google, they said it had a penalty before (2009) and the company behind it that owns gambling .com dropped it as they weren't able to rank it well.
That would be to do with what they wrote in their other PM, and which is why they wanted to check the domain for penalties in the Google console:
I ask because there is nothing indexed atm + in one of the articles it says: "Media Corp said it didn't know why gambling .com and MYDOMAINABOVE .co.uk had been punished by the search engine giant" (but this was in 2009 so hopefully there is no "spam penalty" there now)
No manual penalty was found in the Google console, and they said it was ok with them because they hoped that even with a possible penalty, it would still pass link juice to their other sites in that niche, and that putting a site on the domain and ranking it was not part of their plans.
Just letting people know so that they can decide whether to bid or not, and I'm quite happy if
@j4md0nut wants to withdraw his £100 bid, will PM him with update now.
