I saw this one on IG, X and they said on their TG they run token pumps, where they will list a token address, then after that get influencers to promote the token, pay for mass adevrtising and really pump the token.

Now the thing is I watched several of these, and I noticed something. He posts the contract address at 8pm est, BUT if you look at the token chart you will see that it pumps hard just before he posts the address. so it looks like someone has made a buy, to pump the coin value (or some other method like adding liquidity (not sure about this!), then he starts posting hype messages on TG like look guys its really pumped hard, to make it look like lots of ppl are buying because of his post. he then waits till it pumps bit more, cos of any victims buying in, he then pulls out his investment and profits, the value plummets, but he then carries on hyping the group saying dont worry about the dips its normal, im going to start round two of ads, hey i got the devs to help too, then ppl buy in, value starts pumping a bit more, then he pulls out rest of his tokens, value start plummeting.
pretty sure thats what he is doing for most of his 'signals'
On BSC i think the advice was to due due diligence where you check the contract, check if liquidity is locked in, check if dev has set any dubious contract code like being able to halt sells later. but yeah they getting more advanced, using the money they robbed to inflate new tokens to look legit with bigger liquidity and ads
